Brand-Specific Dilution Calculator
Select your chemical and bottle size to get the exact mix measurements. No more guessing ratios.
Why Standard Dilution Math Risks Your Detailing Jobs
If you have ever tried to clean delicate Alcantara or prep a surface for a ceramic coating using the wrong chemical ratio, you know how disastrous it can be. Standard dilution calculators only do the basic math, assuming you already know the exact ratio you need.
But real auto detailers don’t just ask, “How do I mix 1:10?” They ask, “What is the recommended ratio for Koch-Chemie Pol Star on heavy interior dirt?”
That is why we built this brand-specific detailing dilution calculator. It eliminates the guesswork by directly pulling manufacturer-recommended ratios for the industry’s top chemicals, ensuring you get the perfect mix of water and product every single time.
Popular Detailing Chemical Ratios Explained
Different surfaces require different chemical strengths. Using full-strength All Purpose Cleaner (APC) on leather can strip the dye, while using a highly diluted wheel cleaner on baked-on brake dust is a waste of time. Here is a breakdown of how the pros mix their top products:
Meguiar’s All Purpose Cleaner (D101)
- Heavy Duty (1:4): Best for engine bays, tires, wheel wells, and heavily soiled floor mats.
- Medium Duty (1:10): The standard mix for general interior cleaning, carpets, and vinyl surfaces.
Koch-Chemie Pol Star (Po)
- Heavy Dirt (1:5): Ideal for heavily stained seats and carpets.
- Medium Dirt (1:10): The go-to ratio for standard interior fabric and leather cleaning.
- Light Maintenance (1:20): Perfect for delicate textiles like Alcantara and suede.
CarPro Inside
- Heavy Cleaning (1:1): For neglected leather and heavily soiled plastics.
- General Interior (1:5): Safe for regular maintenance on dashboards, door panels, and finished leather.
P&S Brake Buster
- Heavy Brake Dust (1:0 / Full Strength): Use straight out of the bottle for neglected, heavily coated wheels.
- Standard Cleaning (1:5): Highly economical for regular maintenance washes and light dust.
The Golden Rule of Mixing Chemicals
Always add water to your spray bottle first, then add the chemical.
If you pour the detailing product into the bottle first and blast high-pressure water on top of it, you will create a massive volcano of foam. Not only does this make a mess, but you also lose expensive product and throw off your meticulously calculated dilution ratio. Use our tool above to find your exact water and chemical measurements, fill the water to the designated line, and gently pour your chemical in last.
Frequently Asked Questions (FAQ)
What does a 1:10 dilution ratio mean?
A 1:10 ratio means you mix 1 part chemical to 10 parts water. This creates a total of 11 parts. For example, if you want to fill a 32 oz bottle, you divide 32 by 11 to find your “part size” (approx 2.9 oz). You would use 2.9 oz of chemical and 29.1 oz of water.
Can I use this calculator for snow foam cannons?
Yes. Simply select the “Custom Ratio” option in the dropdown menu. Input the ratio recommended by your snow foam manufacturer (often 1:5 or 1:9 for heavy foam) and set your bottle size to your foam cannon’s capacity (typically 32 oz or 1000 ml) to get the exact measurements.
Why is my APC leaving a white residue on plastics?
Leaving a white residue usually means your dilution ratio is too strong (too much product, not enough water), or you let the chemical dry on the surface before wiping it away. If you are experiencing this, use our calculator to bump your mixture up to a 1:10 or 1:15 ratio.
Does temperature affect chemical dilution?
While temperature doesn’t change the math of the ratio, it does affect chemical performance. Warm water can activate the cleaning enzymes in APCs and fabric cleaners faster, making them more effective. However, never apply chemicals to hot exterior panels, regardless of your dilution ratio.
