Multi Purpose Cleaner Dilution Ratio: How to Mix & Use Car APC
October 31, 2026 by Clean My Vehicle
For general vehicle cleaning, dilute Clean My Vehicle Multi Purpose Cleaner 10:1 — 10 parts water to one part cleaner. For heavier soiling, a stronger solution can be used where required. Start with the weaker solution where practical, test unfamiliar or delicate surfaces first and do not allow the cleaner to dry on the surface.
Concentrated multi purpose cleaner is useful because one product can cover numerous vehicle-cleaning jobs while allowing you to adjust its strength according to the amount of dirt you are dealing with. The important part is understanding what a dilution such as 10:1 actually means and using the cleaner appropriately for the surface.
What Does a 10:1 Dilution Ratio Mean?
A 10:1 dilution means 10 parts water to one part concentrated cleaner.
You do not need specialist measuring equipment as long as you keep the proportions consistent. For example, 100ml of cleaner mixed with 1,000ml of water follows the same 10:1 ratio. For a smaller quantity, 50ml of cleaner plus 500ml of water uses the same ratio.
Remember that these examples produce more total solution than the amount of water alone because the concentrate is being added to it.
What Multi Purpose Cleaner Dilution Should You Use?
For routine cleaning with Clean My Vehicle Multi Purpose Cleaner, 10:1 is the recommended general-cleaning starting point.
That makes it a sensible first mixture when the surface does not require unusually heavy cleaning. If the contamination is more stubborn, the product can be mixed stronger as required. Rather than automatically reaching for the strongest possible solution, increase the concentration only when the cleaning job needs it.
This approach can also make concentrated products practical for professional valeters who use significant quantities of cleaner.
How to Mix Car Multi Purpose Cleaner
Start with a clean, appropriately labelled spray bottle or container. Add the required amount of water and cleaner for your chosen dilution, close the container securely and mix according to the product instructions.
If you regularly prepare several chemicals for professional valeting, clearly identifying each bottle and its dilution reduces the chance of using the wrong product or strength.
The UK Health and Safety Executive guidance on using chemicals at work explains why businesses should assess and control risks from chemical products and make use of the relevant safety information.
Where Can You Use Multi Purpose Cleaner on a Car?
A versatile car APC can reduce the number of separate cleaners required for everyday valeting, but “multi purpose” should never be interpreted as permission to use a product blindly on every material.
Clean My Vehicle Multi Purpose Cleaner is a professional-strength, non-caustic concentrated cleaner designed for a wide range of vehicle-cleaning applications. Apply the appropriately diluted solution using a suitable spray bottle, cloth or cleaning method, agitate where required, then wipe away or rinse as appropriate for the surface.
Always test an unfamiliar or delicate surface in an inconspicuous area first and do not allow the cleaner to dry on the surface.

Should You Use APC on Car Interiors?
Multi purpose cleaners can be useful for suitable interior cleaning jobs, but interior materials vary considerably. Avoid assuming that one dilution is appropriate for every dashboard, fabric, trim, screen or delicate finish. Start cautiously, test first and use a dedicated product when the material requires specialist care.
For fabric and upholstery-specific jobs, consider Foam Upholstery Cleaner 500ML. For interior plastic trim, Clean & Sheen Plastic Cleaner & Renovator provides a more targeted option.

Can You Make Multi Purpose Cleaner Stronger Than 10:1?
Yes. Clean My Vehicle’s current product instructions allow a stronger solution for heavier soiling.
The key is to increase strength because the job requires it rather than assuming stronger always means better. Use the weaker recommended solution where practical, follow the product label and safety information, test when suitability is uncertain and avoid allowing the solution to dry on the surface.
How Should You Wipe Away Cleaner?
The correct removal method depends on the area being treated. Some jobs will require wiping, while others are more appropriately rinsed. Follow the instructions for the surface and avoid leaving chemical residue behind.
For wiping and finishing suitable cleaned surfaces, a clean Blue Microfibre Cloth 320gsm is a useful addition to the valeting kit. Keep cleaning cloths clean and separate from cloths previously used with polishes, waxes or other products where cross-contamination could affect the finish.
Why Dilution Matters for Professional Valeters
For a professional valeter, dilution affects far more than cleaning strength. Correctly mixing concentrates helps maintain consistent results between vehicles and makes it easier to understand how much usable cleaning solution you are getting from bulk product.
Clean My Vehicle Multi Purpose Cleaner is currently available in 1L, 5L, 25L, 200L and 1000L sizes, meaning the same concentrated cleaner can suit occasional home users through to higher-volume professional operations.
Businesses using cleaning chemicals should also consider their responsibilities under COSHH. The Health and Safety Executive COSHH guidance explains how employers should control exposure to substances that can cause ill health.
Multi Purpose Cleaner Dilution Ratio: The Simple Answer
For Clean My Vehicle Multi Purpose Cleaner, start at 10:1 for general cleaning — 10 parts water to one part product.
Use a stronger mixture when heavier soiling genuinely requires it. Test unfamiliar surfaces first, follow the label and safety information, and do not allow the cleaner to dry on the surface.
That gives car owners and professional valeters a simple starting point while retaining one of the main advantages of buying a concentrated cleaner: the solution can be adjusted to suit the cleaning job.
