I did about 2400 s/f of ceramic and quarry tile last week end.
I used Viper Venum, Oxi-Blaster and a small amount of Restore (ran out).
Scubbed with a rotary, rinsed with 1200 psi., some areas twice, and it is still stained/blotchy and efflorescence now.
It is an industrial hydralic parts distributor. The tile is a lunch room the employees use is ceramic and the visitors entrance is quarry.
I have done one grout color job (residential) but it was spotless after I cleaned it.
Will the Grout Perfect cover blotchy/stained grout or do I tell my customer there is nothing else to do but cut out and re-grout? Or is there another possibility for cleaning it up??
