LESLIE: Going to NYC to Robert. Talking about grout. What can we do for you?

ROBERT: Yes, I’ve been trying to clean the grout in my bathroom and I’m having problems. I use bleach and all. Won’t come clean.

TOM: Have you tried to use a grout stripper? Not a grout cleaner but a grout stripper.

ROBERT: No.

TOM: Yeah, that’s the big guns, Robert. And it’s available at home centers. When the grout cleaners don’t work; when the cleaning chemicals don’t work you go for the grout stripper. It’s more caustic. You have to put it on with rubber gloves. You should wear safety glasses and long sleeves. But you put it on the grout. You let it sit for 10, 15 minutes. Follow the label directions. And that really does a really good job of eating through the soap scum and everything else that discolors grout.

LESLIE: That discolors it. And then once you’ve got it clean to a point where you like it, Robert, then go ahead and put a grout sealer on top of it. Because then it won’t get dirty anymore.

ROBERT: OK. I thank you very much.
