I have a lot of tile with light grout in my house and a dog with vomiting issues. What can you suggest as a good grout cleaner? Thanks for the help
Comet cleanser and a toothbrush are what I use. Yes, it's very labor-intensive (and boring).
Is your grout sealed?
Best thing I've found so far is Black Diamond Ultimate Grout Cleaner. I ordered it from QVC. Pricey...I believe it was around $15 plus shipping for 2 bottles. Spray it on, wait a few minutes, and then scrub a bit. You'll see the dirt come off, and then just rinse.
Gave one bottle to my daughter today...she couldn't believe how nice her grout looks now. My grout is darker, so the results weren't as visible, but still better than anything else I've tried... plus it doesn't smell bad.
