Zep Grout Cleaner and Brightener and Easy to Use Handheld Brush - 32 oz (Case of 2) - ZU104632 - Deep Cleaning Formula Removes Old Stains From Grout

I love this stuff. It does such an amazing job of cleaning my white grout. ( What idiot puts white grout on a floor?) Well whoever built my house did and keeping it clean with a house full of kids and animals was impossible until I found this product. The directions say to use a scrub brush, which I did the first time I used it, but since then, I've been able to just squirt it on the grout (the bottle has a small opening making it easy to apply directly into the grout line) then just mop and rinse. Also cleans the tile very well

Easy to use works well on grout and on floor

Finally found a product that actually cleans grout! Cleaned perfectly, it looks brand new. I knew mine was dirty, but really didn't know how bad it was until I tried this. Check out the before and after pics.

I was very disappointed in this product. I tried it multiple times (thinking that maybe it needed more than one treatment to work). Did work at ALL and smelled absolutely horrible. They should really make a warning about the smell. It was repulsive and very hard to get rid of after.

Husband complained of the smell while I was using it. So happy with the outcome and a little sweat equity. Can see it working right away and bubbles/turns white when applied. Worked on grout and tile fixing them both new life!

I saw a video of this stuff cleaning grout just by pouring on. Unfortunately that was not the case for me. It did help clean and brighten but required a lot of scrubbing. I eventually had to use a product with bleach. To be fair, we recently purchased our home and I really don’t know when the grout may have been cleaned

Love the grout brush it comes with and this product works well on my shower. BUT, read the directions and use plastic gloves. The smell is a little overwhelming but it worked on my gray shower grout.

Works so well.
