Fairy liquid (or any washing up liquid) usually contains both bleach and ammonia which affects the wax, and once that protective layer is gone water-based pains turn dull and can crack quite easily. Therefore it is not recommended to use fairly liquid (or any washing up liquid) to clean your car.

It is a question that is commonly asked by people who are just getting into detailing, likely because they know washing up liquid cleans dishes well, so why not a car? Once you dive deep into the research, no matter where you look online you’ll find masses of people stating that it is an extremely bad idea – and it is.
It is, therefore, recommended that you never use washing up liquid to clean a car, and only stick to car shampoos. Some forums have multi-page discussions on what they used to do in the 1970s, and debate between each other to provide proof that it does/doesn’t damage. A nice sentence to end that discussion is – Fairly Liquid is for washing dishes and car shampoo is for washing cars.
Manufacturers such as Autoglym, Meguiars, Bilt Hamber etc spend money and time researching the best possible car shampoo for your vehicle. Car shampoos offer protection to UV exposure, salt, oil, petrol etc. Car shampoo isn’t expensive, and for peace of mind that it wont ruin your paintwork its just worth purchasing. There is zero point to purchasing any form of detailing spray, wax, sealants etc if you’re going to ruin it using washing up liquid that is next to the sink!
Below we’ve listed a few of our reccomended Car Shampoos…
- Bilt Hamber Auto Wash
- Meguiars Gold Class
- Autoglym Polar Wash
- Mer High Shine Shampoo
- Meguiar’s NXT Car Wash
…stay away from the washing up liquid!
