I happen to read an ex-cancer patient's blog on this charity car wash, she commented that it was very gentle to her sensitive skin. when I browse through SgCarMart, I decided to give this product a try by emailing the merchant. At first, I was quite skeptical w waterless car wash as I don't believe it can really clean my car, after trying I realise it was really easy to use and was quite surprise with the shine it gives to my car. like what I've read on the blog, its really quite gentle to my skin. maybe you guys can give it a try, I am looking at trying the 3-wax formula for a after care.
