Discoloration of grout - hard to clean


I used bright white, sanded grout for a bathroom tile floor (porcelain). There are several places where the grout is a slight orange-ish color.

It has proved very difficult to clean. I have scrubbed with cleaners such as soft scrub, even straight bleach.

Can you offer any advice? I would like to get the grout bright white again and will be using a better sealer next time to (hopefully) prevent the discoloration from occurring in the future.

Bright white always looks great when first installed, and then goes downhill very fast.

I was going to suggest the straight bleach, since you can't really bleach out Bright White, but you already tried that.

The only thing I can suggest is after a very thorough cleaning, seal with a Bright White colorseal.

Try the Grout Perfect website to find it. You can do it yourself if your a do it yourselfer.

Just google Grout Perfect and buy a quart of Bright White colorseal, some shammy's and go for it.

You will love your grout once it's colorsealed and it will be a snap to keep clean.

Let me know how it goes and post tome before and after pics. Don't be afraid, you can do it.

Good luck!
