Customer had a radiator shite the bed and leak out onto a brand new carpet. We’ve got browning, dirt, grime, and possibly rust along with mildew going on…….these are the pics he sent. Pad is getting replaced and he’s not wanting to replace the carpet. What chems would you start out with? Obviously we need an acid and rust remover along with maybe something else but I’m trying to not run the gambit on everything as far as chems.
