Hi guy's I've been called to look at a job where the slate hadn't been sealed prior to grouting. It's mostly fine, but you can notice in the rise and falls of the slate where the grout has nestled into some of the grooves. It was sealed afterwards. In attempting to clean this I was considering taping off all other tiles and doing a mild acid wash to try and get through the sealers and scrub clean the grout. Any advice would be extremely welcome? Will it effect the coloring of the slate?
Many thanks
