W2 Multi-Purpose Cleaner for Cars, Matchless Cleaning Power, Biodegradable, Supreme Dirt Removal - 5000ml

It was expensive for the amount received and was completely ineffective against the stain I tried to remove.

Best on the market, no question 👌

Works very well

Used it to clean the roof of a second hand Audi A3 Cabriolet. Did a great job and easy to use. Also has many other uses as a 'cleaner'. It might be a bit more expensive than other makes but does its job well.

A little goes a long way when diluted to the recommended level. I use this around the car & in the home for general cleaning and detailing, It's great stuff that does exactly what it says on the bottle. Highly recommended for all sorts of small area cleaning and degreasing...

Cleaned my roof with two applications which removed most of the moss and dirt accumulated over a year and a half. There are still stubborn patches of dirt which I am sure will be removed with another application. Great product and better value for money than another brand I have tried as there is still 3/4’s of the bottle left
