Is it brown or honey color??
I have some stuff here, it's called "car wash" but it's actually used in industrial car wash facilties. It's high alkalinity (will leave white salt residues if left to dry) I use it for removing brake dust from wheels and removing heavy contamination and such but it WILL destroy your paint if you don;t water it down or leave it on too long. In fact, it will even remove the ceramic paint on the inside of an oil barrel (had some stuff soaking in a barrell with that stuff in it and was wondering what the white specles were...it was the paint)
