Zep Grout Cleaner and Brightener 32-oz

Does what it’s supposed to do

Got in there and removed the buildup between the tiles

Great grout & tile cleaner!

This product removed really bad dark tile stains in a shower that had not been used in a long time. It foamed up quickly and you could see the dirt and grime coming off before I even scrubbed it. Made a huge difference in the tile.

Does what it’s supposed to

This stuff does definitely brighten the grout, but it will also lighten the color of your tile if you’re not careful. I recommend doing small areas at a time so you can focus on the grout lines specifically

Grout cleaner

Excellent product

Good enough

Worked Great on Arctic white grout that was only Nine months old. I have beige and grey colored grout and that is over eight years old and probably 20 years old on the gray grout or more and it took 2 to 3 tries, but it definitely helped make it look clean.

Terrible application

I was concerned about the squeeze bottle application and rightfully so. This is liquid and it gets everywhere! You have to use so much to get it in the grout lines when doing a shower. Don’t let it pool up at the bottom or the acid may damage the surfaces. I have tile wall that had a vent, and it rusted the vent where it got on it. This should be a gel like toilet bowl cleaner with a similar application nozzle, that would be so much better.
