Mapei UltraCare Heavy-Duty Stone, Tile & Grout Cleaner 32 oz. bottle

Not doing anything, same soap not effective at all

Used this on a area in my kitchen, and I did an area with just my steamer. The area with the grout cleaner came out much better and it was easier to use with a scrub broom rather than having to concentrate on the grout lines with the steamer. Hopefully, with regular steam cleaning, I wont have to put as much effort in as I did today. I final mopping with some clean water and it looks great.

Nettoyer les joints de céramique ds la salle de bain. Merveilleux!

Good product only smel

It worked like a dream. Will be ordering more to keep my floor looking new

Tried out this diluted 1:2 for deep cleaning as instructed. First spot I tested, I left on for 10 minutes before scrubbing. I'm using my mom's old denture brush which works out perfectly since the head has angled and strong bristles.I then applied more with the brush and started scrubbing without waiting. Turns out I didn't need to wait, results were about the same.I wouldn't say it brought my grout back to 100% original whiteness but it's pretty close, maybe 90 -95%, which is the best I've seen so far, and I've tried a lot of grout cleaners.It does get slippery so be careful when wiping up or you could slip and fall. Scent is very light, not overpowering like some other cleaners.Pretty good product. Going to keep it and help keep my bathroom floor clean.
