Question

What product is good for removing urine stains from quarry tile and grout? I used a quarry tile & grout cleaner, scrubbed, and pressure washed at 1200 PSI and still it came back along with efflorescence. I assume stains around the base of urinals are caused by urine.


Answer

Acidic cleaners work well on water stains, efflorescence, and urine. If there is oil, grease, or other soil loads, it works better to clean with an alkaline tile cleaner, rinse, and then use the acid cleaner.
