Hydro-Force - Viper Venom - Tile & Grout Cleaner - Ceramic Tile - 1 Gallon - CR22GL

Use according to directions and Do No Use on Polished Marble.

Finally! A grout cleaner that doesn’t leave a horrible messy residue on my floors. This worked very well. I sprayed it on the grout and wiped it up 5 min later and it was much cleaner.

One of the best grout cleaners

I haven’t cleaned the grout in my floors for years and man this stuff works wonders.

The product work good, but u must scrub the grout, and leaves soap residue behind, I used a th40 turboforce tile spinner at 1,000 psi.

I also ordered a lawn and garden sprayer and a long handled scrub brush. If you’re getting years of built up grime off your floor, you will need these things My floor looks as good as new, following the directions on the bottle.

Didn’t clean well. Was hoping for better results.

When my wife and installed our tile floor, we opted on using pure white grout. It looked really nice. We never gave any thought to if it would be hard to clean. This, we should have done.The kitchen floor grout had not been cleaned for about 2 years. We were too busy renovating the rest of our house to worry about a deep cleaning of the tile floors and grout. Now that the house renovation has ended, we are cleaning the grout and it is DIRTY.We have tried numerous home remedies as well as other grout cleaners Amazon sells. Some cleaned better than others, but the grout did not return back to the brilliant white color we wanted. As a last resort, we tried Viper Venom and boy, does it clean! We could see the grime disappear right before our eyes! Yes, like all the other grout cleaners, scrubbing was required, but there was a lot less scrubbing.We tried using this with water at room temperature and it worked great. But it the instructions said to use hot water and when we did, it worked a lot better. To make things easier and faster, we also used the brushes you attach to a cordless drill. Honestly, nothing else came close to this grout cleaner, even when using it with room temperature water. This stuff works!
