Greetings. I have a client that has orange staining on her bathroom floor that we have determind was caused by spray sunscreen. What would be the best chemical to make a poltice for this. I have used mek for this with some success but this one is deep and strong so I think I'll need to poltice it. I also need a recomendation for a homeowner product to keep the mold in they're shower in ckeck. Thanks
