The GOAT of grout cleaners. And I’ve tried them all. This works quickly, no odor, very little effort needed. And I’m a 69 yo woman. Wish I had found this decades ago. Great product. Worth every penny.

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!
