Gtechniq W2 Multi Purpose Automotive Cleaner 500ml - Removes Stains with Ease, Versatile Use On Any Surface - Breaks Down Bonds Between Dirt and Vehicle, For a Clinically Clean Finish

Nickel pour dégraisser avant de traiter avec un rénovateur plastique

I used this for my car roof. It’s potent stuff and I diluted to a 3:1 ratio which was plenty strong enough. It’s much quicker than using the Renovo cleaner I had previously. I did find it a pain to remove from glass though so be careful of overspray. I’ll be buying more and finding other things to clean! It really is great

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.

I have a Mercedes convertible and my roof has not really been up to scratch for a long time. Went online to buy my usual product and found that Gtechniq had been rated higher!! I bought 0.5 litres and used it "neat".....I could not believe how much "filth" flowed when I rinsed off the Cleaner. My roof is still not perfect, and as I had used the whole lot, I have ordered 5 litres and will use it 50/50 the next time. I would certainly recommend W2 for this purpose and I think it is a great product to have in your home for anything stubborn, even if you do not own a convertible :-)

Best on the market, no question 👌
