How do I clean grout?

Clorox soft scrub or Tilex with a nylon scrub brush. After clean and dry, apply a grout sealer.

I Clean Tile &Grout for a living, the BEST way to do it is with a Acid based Cleaner, I use THE WORKS Toilet Bowl Cleaner Full Strength , put it on the Floor, let it sit for 5 - 10 minutes, and take a Scrub pad to it "Corse" and use my Foot to Scrub it, and Mop it up. " just watch out for the Fumes " and for the Grout Sealer, it's your choice, but it's a waste of time & money, it doesn't do anything, your Grout is going to get dirty regardless.

Bar keepers friend and a toothbrush.

Bleach and a hard scrubbing brush work best for me.

This is the shower cleaner that we use to help keep grout and tiles clean and minimize the mildew. Hope this helps! Hugs, Holly
