Dilution Ratio Calculator
Getting dilution ratios right is one of the most overlooked parts of car detailing. Use too little product and cleaning performance can suffer. Use too much and you waste product, increase residue, and in some cases make a product harder to work with.
The problem is most people misunderstand how dilution ratios actually work.
A common mistake is thinking a 1:10 dilution means 10 total parts. It does not. A 1:10 ratio means 1 part product and 10 parts water — making 11 total parts altogether. That confusion alone is why so many detailing products are mixed incorrectly.
Our Dilution Ratio Calculator removes the guesswork. Whether you're diluting snow foam, APC, wheel cleaner, shampoo, or quick detailer, simply enter your ratio and bottle size to calculate exactly how much product and water you need.
How to use this calculator
Pick a mode
Simple uses Duel's own recommended dilutions. Advanced lets you dial in any ratio.
Build your mix
Choose a product, a strength and a container size — or set your own ratio and total volume.
Read the result
You'll see exactly how much product and water to combine. Tap Copy recipe to save it.
Pro tip
Always add the product to the water, not the other way round. It mixes more evenly, foams less, and stops concentrate splashing on you or your paintwork.
Pick your mix
e.g. 1:10 means 1 part product to 10 parts water.

What Does a 1:10 Dilution Ratio Mean?
A 1:10 dilution ratio means:
- 1 part product
- 10 parts water
- 11 total parts combined
For example, if you want to make 1 litre of ready-to-use solution at 1:10, you would need:
- 90.9ml of product
- 909.1ml of water
This is where many people get caught out. They assume 1:10 means:
- 100ml product
- 900ml water
But that is not technically a true 1:10 dilution.
The calculator above does the maths properly for you instantly, helping avoid wasted product and inconsistent results.
Why Dilution Ratios Matter
Correct dilution is not just about saving money. It directly affects:
cleaning performance
safety on sensitive surfaces
foam behaviour
residue levels
product longevity
repeatability
One of the biggest myths in detailing is that stronger dilution automatically means better cleaning. In reality, over-concentrating products often creates more problems than it solves.
Too much APC can increase the risk of staining or leaving a residue on interior surfaces. Excessively strong snow foam can reduce rinse performance and waste product. Even shampoos can behave differently when overloaded.
The best detailers are not the ones using the most product. They are the ones consistently using the correct amount.
Common Detailing Dilution Ratios
| Product Type | Common Dilution |
|---|---|
| Snow Foam | 1:5 – 1:15 |
| APC | 1:4 – 1:20 |
| Wheel Cleaner | Product dependent |
| Interior Cleaner | 1:10 – 1:20 |
| Shampoo | Product dependent |
| Quick Detailer | Usually ready to use |
These are starting points only. Heavier contamination may require stronger dilution, while maintenance cleaning often works perfectly with weaker ratios.
Quick Dilution Examples
| Ratio | Bottle Size | Product Amount | Water Amount |
|---|---|---|---|
| 1:5 | 500 ml | 83.3 ml | 416.7 ml |
| 1:10 | 1 litre | 90.9 ml | 909.1 ml |
| 1:20 | 750 ml | 35.7 ml | 714.3 ml |
Common Dilution Mistakes
Mixing Ratios Backwards
This is by far the most common issue. A 1:10 dilution does not mean:
- 1 part water
- 10 parts product
It means the exact opposite.
Using Too Much Product
More chemical does not always equal more cleaning power. In many cases it simply creates:
- more residue
- unnecessary waste
- poorer rinse behaviour
- harder wipe off
Ignoring Bottle Size
The same dilution ratio produces completely different amounts depending on the bottle being used. A 500ml trigger bottle and a 5L pump sprayer require very different volumes of product.
Assuming Thick Foam Means Better Cleaning
Thick foam photographs well on social media. That does not automatically mean better performance.
Good snow foam is about lubrication, dwell time, cleaning ability, and rinse behaviour — not simply creating shaving cream.
Recommended Dilution Ratios for Duel Products
Assault Snow Foam
For regular maintenance washes, Assault typically performs well around:
- 1:10 to 1:15 in a foam lance bottle
Heavier winter contamination may benefit from stronger dilution.
Logic Interior APC
Logic is designed to be versatile. Typical starting points:
- 1:20 for light interior cleaning
- 1:10 for heavier contamination
- stronger only when genuinely required
Axis Wheel Cleaner
Wheel contamination varies massively depending on driving conditions and wheel protection.
For maintained wheels:
- weaker dilution is often sufficient
For neglected wheels:
- stronger ratios may be needed initially
Bahama Shampoo
Shampoo performance is heavily affected by water quality, wash method, and protection layers already on the vehicle.
Overloading shampoo rarely improves results and simply increases product usage.
Nitty Quick Detailer
Quick detailers are generally designed ready to use and should not normally require additional dilution unless specifically stated.
Dilution FAQs
Everything you need to know about diluting your products.
What is the easiest way to calculate detailing dilution ratios?
Using a dedicated dilution ratio calculator is the fastest and most accurate method, especially when working with different bottle sizes and product strengths.
Does stronger dilution mean better cleaning?
No. Over-concentrating products can reduce performance, increase residue, and waste product unnecessarily.
Should dilution ratios change for heavy dirt?
Yes. Heavier contamination may require a stronger mix, while maintenance cleaning usually works best with lighter dilution.
Can dilution ratios affect foam levels?
Absolutely. Product concentration, foam lance setup, water hardness, and pressure washer performance all influence foam production.
Should APC always be diluted?
In many cases, yes. APCs are often designed to be adjusted depending on the surface and contamination level.
Does warm water affect dilution?
Warm water can help some products mix more evenly, particularly in colder temperatures, but the actual dilution ratio itself remains the same.
Get Better Results With The Right Mix
Most detailing products do not fail because the chemistry is poor. They fail because they are used incorrectly.
Understanding dilution ratios helps you:
clean more safely
waste less product
achieve more consistent results
improve efficiency
get the best performance from your products
Whether you're using snow foam, APC, shampoo, wheel cleaner, or quick detailer, the right dilution ratio makes a bigger difference than most people realise.
