Tubo 1 Report post Posted January 17, 2018 Hi all: I just completed my floor tiles works. My contractor suggest me to do Acid wash. But i checked something and decide not do it. Because it seems that the Acid wash may affect the grout line material between tiles (changing color to white). Even my tiles is light yellow homogeneous and grout material is also very light yellow. i still didn't do Acid wash. Is there any cleaning product can clean the cement marks on tiles? have to without affect the grout line. I searched something like HG things below. I don't know is it really helpful. anything or method? Share this post Link to post Share on other sites
