Mix the Right OMNIA 2.0 Strength for Every Interior Job

By Marco Reyes, former professional detailer · Updated September 1, 2026

Methodology: This guide prioritizes current manufacturer instructions over retailer charts, demonstrations, and generic dilution calculators. Always verify the ratio and safety directions on your own container before mixing.

Quick answer: use 1:10 for ordinary interior cleaning

For ordinary or maintenance interior cleaning, the stated starting dilution is 1:10. Under the usual product-to-water convention, that means:

• 1 part OMNIA 2.0
• 10 parts water
• 11 total parts

One part out of 11 total parts is approximately 9.09% concentrate, so 1:10 does not mean the finished solution contains 10% product. Manufacturer and retailer guidance identifies 1:10 for ordinary cleaning, but the current container remains the controlling instruction (OMNIA 2.0 dilution guidance).

There is an important caveat: the supplied manufacturer pages display ratios such as 1:4, 1:7, and 1:10 without defining the components in words. Before mixing, confirm that your bottle label, warning sheet, or technical documentation uses the usual product-to-water interpretation. Regional or revised instructions may differ, and current documentation overrides this guide.

For a routine clean:

1. Confirm that 1:10 is appropriate for the surface and task.
2. Measure one part concentrate for every ten parts water.
3. Apply a controlled amount without unnecessarily saturating the surface.
4. Wipe with a clean microfiber cloth.

Stronger mixtures are reserved for defined intensive-cleaning, leather, equipment, or plastic-restoration uses. They are not automatic upgrades for every visibly dirty interior.

OMNIA 2.0 dilution chart by cleaning task

Use this chart to select a task before calculating the batch. Do not assume that every concentration is suitable for every material.

Task	OMNIA 2.0 ratio	Intended use	Application method
Stubborn contamination or plastic restoration	Pure or 1:1	Exceptional treatment for stubborn dirt or specified faded, vintage, or improperly washed plastic	Cleaning and restoration methods differ; the documented restoration process uses brush application, a longer drying period, and controlled removal
Extraordinary cleaning	1:2	Intensive cleaning when the ordinary dilution is insufficient	Spray, agitate with a brush or soft-bristle brush to create foam, then remove with a dry microfiber cloth
Leather cleaning	1:4	Manufacturer-designated leather dilution	Apply conservatively and follow the current label’s removal directions
Tornador or RotorJet	1:7	Use with the two specifically named cleaning systems	Follow the product label and the equipment manufacturer’s operating instructions
Ordinary or maintenance cleaning	1:10	Standard interior cleaning	Spray the surface and wipe with microfiber
Quick interior cleaning	1:15	Lighter maintenance or quick-cleaning use	Apply sparingly and wipe with microfiber

These task ratios and the ordinary, extraordinary, and restoration methods are drawn from the manufacturer’s published instructions (Labocosmetica’s OMNIA 2.0 instructions).

How to choose from the chart

Ask three separate questions:

1. What surface are you cleaning? Leather has a specific 1:4 instruction.
2. How severe is the contamination? Routine dust and fingerprints do not call for the same process as ingrained dirt.
3. What equipment are you using? The 1:7 instruction specifically names Tornador and RotorJet systems.

Do not select a strong ratio merely because a surface appears durable. Ratio selection should follow the defined task, not a guess about how much chemical a material can tolerate.

The distinction between 1:10 and 1:15 is deliberate:

• Choose 1:10 for ordinary or maintenance cleaning.
• Choose 1:15 for lighter, quick interior cleaning.
• Do not merge the two into an informal range and assume every concentration between them has the same designated use.

Retailer instructions sometimes conflict with the manufacturer. One retailer, for example, lists 1:5 to 1:10 for normal cleaning and 1:5 for leather rather than the manufacturer-supported 1:10 and 1:4 values (Clean and Shiny’s retailer guidance). When recommendations disagree, do not average them. Use the current manufacturer label or technical documentation.

Another retailer extends 1:7 to injection-extraction equipment as well as Tornador and RotorJet systems. That is retailer guidance, while the supplied manufacturer instructions expressly identify Tornador and RotorJet (Alpha Details’ dilution chart). Do not treat 1:7 as official extractor guidance unless current manufacturer documentation specifically permits it.

How to calculate any product-to-water ratio

Under the usual product-to-water interpretation, a ratio of 1:10 contains one part product and ten parts water.

Start by adding both sides:

Total parts = product parts + water parts

For 1:10:

1 + 10 = 11 total parts

For a fixed final volume, use:

Product volume = desired final volume × product parts ÷ total parts

Then calculate the water:

Water volume = desired final volume − product volume

For a ratio written as 1:x, the product formula simplifies to:

Product volume = desired final volume ÷ (1 + x)

Example: a 500 mL final batch at 1:10

1. Add the ratio parts: 1 + 10 = 11.
2. Divide the desired final volume by 11: 500 ÷ 11 = 45.45.
3. Measure approximately 45.5 mL of OMNIA 2.0.
4. Add approximately 454.5 mL of water.

The result is approximately 500 mL of finished solution.

Final volume is not the same as water volume

A common error is to decide on a 250 mL batch, measure 250 mL of water, and then add concentrate. That maintains the ratio but produces more than 250 mL of finished cleaner.

For example:

• 25 mL product
• 250 mL water
• 275 mL finished solution

This is still a 1:10 product-to-water mixture because 250 is ten times 25. It is not a 250 mL final batch. A reviewer’s OMNIA 2.0 demonstration used that exact recipe, providing a useful illustration of water volume versus final volume (Improved Garage’s OMNIA 2.0 demonstration).

To fill a 250 mL bottle without exceeding its capacity, divide 250 by 11. That gives approximately 22.7 mL product and 227.3 mL water.

Why 1:10 is not 10%

At 1:10, the concentrate is one of 11 total parts:

1 ÷ 11 × 100 = 9.09%

Treating 1:10 as 10% would produce a slightly stronger mixture. The difference is modest, but using total parts keeps recipes consistent across bottle sizes.

All these calculations depend on the ratio meaning product-to-water. Confirm that convention on the current label or technical sheet before preparing the mixture.

Exact mixing amounts for common bottle sizes

The following recipes create a fixed final volume at 1:10 under the usual interpretation of one part OMNIA 2.0 to ten parts water.

Desired final volume	OMNIA 2.0	Water	Finished amount
250 mL	22.7 mL	227.3 mL	250 mL
500 mL	45.5 mL	454.5 mL	500 mL
750 mL	68.2 mL	681.8 mL	750 mL
1 L / 1,000 mL	90.9 mL	909.1 mL	1,000 mL
16 US fl oz	1.45 fl oz	14.55 fl oz	16 fl oz
32 US fl oz	2.91 fl oz	29.09 fl oz	32 fl oz

These quantities follow the standard total-parts calculation used by the available OMNIA 2.0 dilution calculator.

These are final-volume recipes. If you instead begin with 500 mL of water, add 50 mL of concentrate to preserve a 1:10 product-to-water ratio. The resulting batch will contain 550 mL.

Calculating the other supported ratios

The next table is an arithmetic reference, not permission to use every ratio on every surface. First select the appropriate task from the manufacturer-supported chart.

Ratio	Total parts	Product share	Water share	Product in a 500 mL final batch	Water in a 500 mL final batch
1:1	2	1/2	1/2	250 mL	250 mL
1:2	3	1/3	2/3	166.7 mL	333.3 mL
1:4	5	1/5	4/5	100 mL	400 mL
1:7	8	1/8	7/8	62.5 mL	437.5 mL
1:15	16	1/16	15/16	31.25 mL	468.75 mL

The listed ratios correspond to OMNIA 2.0’s published task guidance; the volume columns are calculated by dividing the final batch according to the total number of parts (Labocosmetica’s OMNIA 2.0 product guide).

For another bottle size, multiply the desired final volume by the product fraction. At 1:4, product occupies one-fifth of the final batch. At 1:15, it occupies one-sixteenth.

How precise do the measurements need to be?

Practical spray-bottle preparation does not require hundredths-of-a-milliliter precision when the measuring vessel only shows whole milliliters. Round sensibly while keeping the finished amount within the bottle’s capacity.

For a nominal 500 mL batch at 1:10, 45 mL product plus 455 mL water is a practical rounded recipe. The key is to avoid a large ratio error or an overfilled bottle.

Do not substitute 1:20 merely because it appears in a generic calculator or retailer chart. The supplied manufacturer guidance designates 1:15 for quick interior cleaning; the evidence reviewed for this guide does not establish 1:20 as an official OMNIA 2.0 ratio.

Three application workflows after mixing

Dilution determines the concentration in the bottle. The application method determines how the cleaner is worked and removed. Match the process to the chosen dilution instead of using one technique for every job.

1. Ordinary cleaning at 1:10

For ordinary or maintenance cleaning:

1. Remove loose debris where practical.
2. Test a small, inconspicuous area.
3. Apply the 1:10 mixture to a manageable section.
4. Avoid unnecessary saturation.
5. Wipe with a clean microfiber cloth.
6. Turn to a clean face of the cloth as it becomes dirty.

The published routine-cleaning method is to spray the surface and wipe with microfiber. It does not establish a special dwell time, so do not invent one or assume that leaving the cleaner in place longer will improve the result.

Work in sections small enough to maintain control over application and removal. Keeping the cloth clean is general detailing practice rather than a product-specific manufacturer requirement.

2. Extraordinary cleaning at 1:2

Use the extraordinary-cleaning process only when routine cleaning is insufficient and the current instructions permit it:

1. Apply a controlled amount to the work area.
2. Agitate with a brush or soft-bristle brush.
3. Work the cleaner until foam forms.
4. Remove the residue and released contamination with a dry microfiber cloth.
5. Inspect the result before repeating the process.

Labocosmetica distinguishes this 1:2 brush-agitation method from its routine 1:10 spray-and-wipe process (the manufacturer’s OMNIA 2.0 cleaning tutorial). Extraordinary cleaning should not become the default simply because an interior has gone a long time between cleanings.

3. Quick cleaning at 1:15

The 1:15 dilution is the lighter quick-cleaning option:

1. Confirm that the ratio is appropriate for the surface.
2. Apply sparingly to a small section.
3. Wipe with a clean microfiber cloth.
4. Inspect for remaining contamination or residue.

The supplied guidance does not specify a dwell time for this workflow. Treat it as a controlled maintenance wipe rather than allowing the liquid to sit for an arbitrary period.

For all three workflows, fold or replace the microfiber when it becomes visibly contaminated. This is practical technique, not a claim that the manufacturer mandates a particular number of towels.

Do not add unsupported rinsing or dwell instructions where the current documentation is silent. Follow the label’s removal directions for the selected surface and use case.

Leather, Tornador use, and other surface-specific decisions

Leather: use 1:4 unless current instructions say otherwise

For leather, the published manufacturer ratio is 1:4, subject to confirmation on the current label. Under the usual convention, that is one part product and four parts water, or five total parts.

For a 500 mL final batch:

• 100 mL OMNIA 2.0
• 400 mL water

For Tornador or RotorJet systems, the published ratio is 1:7, or one part product to seven parts water under the usual convention. A fixed 1 L batch would therefore contain 125 mL product and 875 mL water. Both ratios appear in the manufacturer’s task-specific guidance (Labocosmetica’s OMNIA 2.0 product guide).

Retailer recommendations for leather vary, including 1:5 and lighter quick-cleaning suggestions. Those third-party values should not replace or be averaged with the manufacturer’s 1:4 instruction.

Before broad leather application, test a hidden section and apply conservatively. Avoid unnecessary saturation around seams, perforations, and adjoining materials. These are general handling precautions rather than manufacturer-prescribed leather techniques.

Tornador and RotorJet: use 1:7

The 1:7 ratio does not replace the equipment manufacturer’s operating instructions. Follow the tool’s filling, pressure, and application requirements as well as the OMNIA 2.0 label.

Do not automatically extend 1:7 to an injection-extraction machine. The manufacturer evidence reviewed here specifically identifies Tornador and RotorJet systems. Extractor suitability, dilution, foaming behavior, and tank compatibility require separate confirmation.

Other interior materials

The manufacturer’s product page names Alcantara, aluminum, carpet, leather, plastic, and fabric. That is a manufacturer compatibility claim, not proof that every coating, dye, repair, or aged variant will respond identically.

Use this decision order:

1. Confirm that the specific surface is covered by the current label.
2. Select the ratio for the task rather than apparent durability.
3. Account for the application equipment.
4. Test an inconspicuous area.
5. Begin with controlled application.
6. Inspect the result before expanding the work area.

Do not interpret broad “interior” compatibility language as approval to spray screens, switches, ports, speakers, or other electronics directly. The supplied manufacturer evidence does not specifically identify electronics as approved direct-spray surfaces.

When undiluted or 1:1 use is appropriate

Undiluted OMNIA 2.0 and a 1:1 mixture are exceptional treatments. Published guidance reserves them for stubborn contamination or restoration work involving faded, vintage, aggressively cleaned, or improperly washed plastics. They are not routine-maintenance dilutions.

When ordinary cleaning is insufficient, first determine whether the documented 1:2 extraordinary-cleaning process fits the job. Concentrated plastic restoration is not merely a stronger version of ordinary cleaning; it has a different purpose and application sequence.

Documented plastic-restoration sequence

For the specified plastic-restoration use:

1. Use OMNIA 2.0 undiluted or at 1:1, subject to the current label.
2. Spread it with a brush.
3. Leave it for approximately 10 minutes or until dry.
4. Wipe with a damp microfiber cloth.
5. Dry with a separate clean microfiber cloth.

That sequence is documented for aged or incorrectly washed plastics (OMNIA 2.0 restoration instructions).

Process	Concentration	Purpose	Agitation and removal
Extraordinary cleaning	1:2	Intensive contamination removal	Spray, brush to create foam, then remove with dry microfiber
Plastic-restoration treatment	Pure or 1:1	Exceptional treatment for specified faded, vintage, or improperly washed plastic	Spread with a brush, leave about 10 minutes or until dry, damp-wipe, then dry

Begin with the least concentrated manufacturer-supported option that matches the task. Do not jump from routine cleaning directly to neat product when the job does not meet the restoration criteria.

Test an inconspicuous area and assess the surface after completing the removal process. Do not assume that concentrated cleaner can reverse cracking, abrasion, coating failure, chemical etching, sun damage, or permanent discoloration. “Restoration” identifies the intended treatment category; it is not a guarantee of complete color or finish recovery.

Safety checks and mistakes to avoid

OMNIA 2.0 carries warnings that it causes skin irritation and serious eye irritation and may cause an allergic reaction. Its instructions call for protective gloves, eye or face protection, and keeping the product away from children (Labocosmetica’s product instructions and safety warnings).

Before mixing or using it:

• Read the current bottle label.
• Review the current warning sheet and safety documentation.
• Wear the specified protective equipment.
• Keep the concentrate and diluted cleaner away from children.
• Limit splashing and unnecessary skin or eye contact.

Current product documentation overrides this article, retailer pages, demonstrations, and calculators.

Practical preparation precautions

Third-party general handling guidance recommends using clean water and clean measuring equipment, testing a hidden area, avoiding direct spraying onto electronics, limiting excessive wetting, and not mixing the cleaner with other chemicals. It also recommends labeling the diluted bottle with the product name, ratio, and mixing date (general dilution and handling guidance).

These are general precautions, not evidence of product-specific compatibility or incompatibility with every possible material or chemical.

Do not infer an official mixing order from common detailing practice. The supplied manufacturer evidence does not establish whether water or concentrate must enter the bottle first. It also does not specify a required water type, a diluted-product shelf life, a storage duration, or a complete chemical-incompatibility list. Consult the current label or safety data sheet instead of guessing.

Common dilution and application errors

Treating the written ratio as a percentage. A product-to-water ratio must be converted using total parts; the second number is not automatically the finished percentage.

Confusing final volume with starting water volume. Adding concentrate to a bottle already filled to its nominal capacity will overfill it. Calculate the concentrate as part of the desired final volume.

Defaulting to undiluted product. Neat product is an exceptional option for specified contamination or plastic-restoration work, not the routine starting point.

Blending conflicting retailer ratios into a range. Different third-party recommendations do not create a new manufacturer-approved range. Use the task-specific value in current manufacturer documentation.

Assuming stronger is always better. Choose concentration according to the defined surface, soil level, and equipment rather than automatically escalating strength.

Applying one machine ratio to every machine. A ratio naming Tornador and RotorJet systems should not be extended to extractors or unrelated equipment without confirmation.

Using one dirty cloth throughout the interior. Fold or replace microfiber as it becomes contaminated instead of carrying removed grime into the next section.

Oversaturating the work area. Apply enough solution to complete the selected process without treating additional liquid as a substitute for controlled agitation and removal.

The practical hierarchy is straightforward: check the current label, use 1:10 for ordinary cleaning, calculate it as 11 total parts, and change to another supported ratio only when the surface, soil level, or tool calls for it (current ordinary-use guidance).

Before starting:

• Confirm the surface, task, ratio, and ratio convention.
• Calculate against the desired final bottle volume.
• Wear the protection stated in the current documentation.
• Label the diluted bottle.
• Test an inconspicuous area.
• Avoid unnecessary saturation and direct spraying of electronics.
• Use the microfiber or brush workflow that matches the task.
• Inspect the result before repeating or increasing concentration.

Frequently asked questions

Does 1:10 mean one part OMNIA 2.0 and ten parts water?

Under the usual product-to-water convention, yes. It means one part OMNIA 2.0 plus ten parts water, producing 11 total parts and a final mixture containing approximately 9.09% concentrate. Third-party ratio guidance expressly uses that product-to-water interpretation.

Because the supplied manufacturer pages do not define the components in words, confirm the convention on your current bottle or technical sheet.

How much OMNIA 2.0 do I need for a 500 mL bottle at 1:10?

For a 500 mL final batch, divide 500 by 11:

• 45.5 mL OMNIA 2.0
• 454.5 mL water

If you instead add 50 mL of product to 500 mL of water, the ratio remains 1:10 but the finished quantity becomes 550 mL. This follows the same product-to-water convention demonstrated in a reviewer’s 25 mL product plus 250 mL water batch.

Should OMNIA 2.0 be diluted 1:4 or 1:5 for leather?

Use 1:4, subject to confirmation on the current label. That is the manufacturer-supported leather ratio; 1:5 is conflicting retailer guidance and should not displace it. At 1:4, a 500 mL final batch contains 100 mL product and 400 mL water.

Can OMNIA 2.0 be used undiluted for normal interior cleaning?

No. Ordinary or maintenance cleaning uses a diluted mixture, while undiluted or 1:1 product is reserved for stubborn contamination or specified plastic-restoration work.

Use concentrated treatment only when the job meets those conditions and the current label permits it.

What dilution should I use in a Tornador or RotorJet?

Use 1:7, meaning one part OMNIA 2.0 to seven parts water under the usual ratio convention. That is eight total parts, so a fixed 1 L batch contains 125 mL product and 875 mL water.

Confirm the ratio on the current product label and follow the equipment manufacturer’s instructions. Do not assume that 1:7 is officially approved for injection-extraction machines.
