I love this product. I cleans the toughest indoor grout.

Good product only smel

This stuff is AMAZING!!!!! I order a LOT from Amazon and I don't usually give reviews, but had to share!!! Right picture is before and left is after! I sprayed the solution in the grout and let stand for about 5-10 minutes then scrubbed with a long-handled scrub brush. It has been YEARS since this grout was cleaned and I wasn't sure if I could get it cleaned. My grout is as good as new! Highly recommend this product!!!

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.
