It's very difficult to save the grouts clean, what nature of material can replace the tiles and still be impermeable.
Answers:    Clorox Clean Up does my tiles just fine I used to use 409 but go to clorox clean up it does a better chore. Spray it down and leave for 2 to 5 minutes and wipe it stale. Shines like strange.
any over the counter product will work well
