Help!! Our builder didn't clean the grout (or seal it) on our beautiful 30 x 60 porcelain floor tiles in our ensuite, bathroom, powderoom, or laundry. The grout looks very 'patchy' - powdery white and dark in spots. The grout is supposed to match exactly with the tile colour (medium coffee colour).
Could someone please suggest how we can do this without using harsh bleach or harsh chemicals that may ruin the grout? Are there professionals that can do this for us as it is a largish job? Once this is done we also want to 'seal' the grout. Can professionals also seal the grout for us?
We are organising our 90 day maintenance for the house so, we don't want to do it until all our 'issues' have been fixed. Wouldn't want traddies coming in and out ruining the floors again!
Please help. I can't stand looking at patchy looking grout any longer.......
