How do you carry alot of tile grout bad the floor of your shower. It have be within a month or longer?
Answers: Do not use a putty knife , it can and will hand down aluminum marks which are not removable.. A grout smog remover will help along w/ a WHITE nylon scrub pad.. Large hunks (which should never enjoy been moved out there) can be carefullyy scraped off a bit w/ a flawless stainless steel knife but still be carefull.. GL
Try a putty axe.
