Try and add some good info on the product pictures of before and after, of the product and where you got it from!
Bit more info than it makes stuff Shiney
Ill start

Used this for the first time today and tbh it amazed me how good it is, it water based and containes no acid so is safe on all wheel types (un sure for polished alloy) removed 100% of the brake dust on my wheels even the stuck on bits I couldn't shift with polish/clay

Makes the wheels look like there bleeding too which is cool also found it was great and cleaning the brake dust of calipers too
I got my 1ltr bottle from http://www.elitecarcare.co.uk/bilt-hamb ... Path=25_30
One downside is it don't smell too good
100% recommend to anyone
