nearly every time I go to the car boot there is always someone selling supaguard cleaning products; normally in its own bag..... packaging seems cheap... anyway I decided to use the alloy wheel cleaner on my dad's 07 CLK... wheels have caked on brake dust and no matter what I tried it didn't shift... as again the weather was great today.. thought I would do full detailed clean as well.... put this liquid on with brush onto the wheels and my god.... I was so impressed!!!! absolutely cracking!! I was more than surprised... so much that I wish I had bought more of this product when at the car boot... looked on Ebay and its much more expensive.... I bought the bag with about 10 items from car boot for a fiver... and seems to be the normal price when you go down there..... anyway its a highly recommended... maybe I should use gloves next time!!
