Review: Amazing Product! Excellent Cleaning Power - I used this today in my filthy kitchen tile floor grout. It has years of built up grime. The floor is mopped on a weekly basis, but I cannot remember the last time. The grout had been properly cleaned.I sprayed the product on in sections and let it sit on there for five minutes. I then use the Rubbermaid grout scrubbing brush first and then I used an angled brush that I purchased separately for grout and scrubbed it very well wiped it all down mopped and then used a grout sealer and the results were amazing. Does take some manual labor to do, but it works excellent. Highly recommend there was not a strong odor and I used non-latex Mr. clean rubber gloves and had no issues.
Review: WOW. Years of black tile grout,, Wiped Clean - Happy New Year 26 .. Love This Cleaner ... WOW !! years of black crud shower tile. see photos ... I've been living in this 80's built condo since 2011. The last few years tried EVERYTHING to clean the black around tiles / soft grout / caulk, whatever it's called. NO LUCK .. tried DYI' formulas, tried bleach scrub powder, bleach, mildew remover. NO LUCK. I bought drill attachment brush set a year or 2 ago also, did not help. TODAY, rec'd this product desertcart overnight. I relied on the reviews, best judgement ever on purchase. The brush included worked great on the corners, but I used the mentioned drill attachment for large areas. Yes bought desertcart a while ago, were quite cheap and paid off today. Just look at the nasty black leftovers in tub. 4 hours or more cleaning since the drill battery died after 10-15 minutes per round. Recommended!! I ordered a second bottle just now.

### ⭐⭐⭐⭐ Works Really Well, Just a Few Minor Issues
*by C***. on October 31, 2025*

This grout cleaner is genuinely effective — it lifted years of dirt and grime that other cleaners barely touched! The quality of the cleaner itself is impressive, and the included brush makes it easier to get into tight grout lines. It’s definitely a powerful cleaner that delivers results without damaging tile. That said, the bottle design could be better. Mine had a bit of leakage during shipping, and the solution is slightly sticky when it dries if not fully wiped up. The smell is noticeable but not overwhelming — more “cleaning chemical” than fresh scent. The bottle and spray nozzle feel durable, though, and it should last a while. Overall, a great product for deep cleaning grout — just be mindful of the slight mess factor!
