Zep Grout Cleaner and Brightener - 32 Ounce (1 Bottle) - ZU104632 - Deep Cleaning Formula Removes Old Stains From Grout

First of all let me say, I don’t write many reviews. But when I do, it’s because I feel very strongly about a product. I bought this product as it was a suggestion to go with the long handled grout brush I was buying. And it was $10-ish, so I said, why not?GAME CHANGER!!!! My 400 sf of tile was super clean in about 30 min! Just squirt it on, watch it bubble, then give a little scrub and wipe clean. I used a mop of clean water.Be prepared, this stuff gets dirt out that you didn’t know was there! Floors were so clean.Fumes are a little strong, so have a fan on. But it’s not as strong smelling as Clorox clean up.

I came across a video showing someone using the Zep Grout Cleaner and Brightener to clean a bathtub, and I had to try it. Since I live in a rented apartment, I’m always on the lookout for effective deep-cleaning products—and this one really impressed me.I started by using it on the bathroom tile, which had some water marks and buildup. Then I tried it on the faucet, which looked white and dull from heavy water stains (even though it's supposed to be silver). Finally, I used it on the tub itself, which had old marks from baths over time.It definitely took a bit of scrubbing, but the results were worth it. The cleaner lifted a lot of the grime and restored the surfaces much better than I expected. My bathroom looks and feels so much cleaner now.Highly recommend if you're willing to put in a little elbow grease!

Amazing product. We moved in a place where the kitchen tile grout was never cleaned before. This product turned it to brand new in 5 seconds.The bottle says wait 2-3 minutes after applying the product. It was not necessary for us. I just sprinkle it on the grout, waited 5 second and wiped it off.The only concern I had is that it may left white residue on dark grout. Ours is light grey so not a problem for us.There is definitely chemical smell but not too bad. Definitely need chemical gloves though.

If, like me, you're a guy, and an indifferent housekeeper, you'll find that things like bathrooms can get a little dirtier than you'd like. The grout in the floor tile definitely needed a cleaning. I saw this advertised and decided to give it a try. It works exactly as advertised. The only reason I didn't give it five stars is that it's pretty toxic stuff, and has some level of acid in it, which freaked me out a bit. As per the instructions, I wore goggles, heavy duty rubber gloves, long pants, shoes and a long-sleeved shirt. I even wore a mask because it says it can be bad for people with respiratory issues, which I don't really have, but why take a chance. The bottle sprays out pretty easily so it was possible to get about as much as I needed, where I needed it. I rubbed it lightly on the grout with an old toothbrush to make sure it was sitting where I wanted it to, then left it alone for a few minutes and used the brush to clean it up. The stain came right off. It's nice when a product works the way it's supposed to.

I was pleasantly surprised by this product. I applied it in small areas at a time following the directions and this stuff works well! I found it gross and fun to see how much dirt came out. I will definitely recommend and repurchase.

I clean houses for a living. Oh, stop, I know I live an exciting life! I've used ZEP products for years. I was excited to see this thinking I'd be a wizard of clean grout and my praises would be sung. I was so excited for my new status that I didn't read directions...who does, seriously? I squirted that blessed cleaner of grout into my shower and went to scrubbing. Beautiful, but my grout has been scrubbed within an inch of its life before this purchase. I confidently used it at my clients house. Squirted that stuff up and down this 2 year old shower. (New home) I scrubbed and rinsed and was happy. (Shower was still drip drying.) 2 weeks later...I go back to my clients (new((ish)) home. I cheerfully greet my client and headed to the master bath, my first stop that cleaning day. I open that glass shower door and hiccup/gasp! There are waves of matte tile on each shiny tile. I'd liberally and confidently squirted this cleaner (read acid) on beautiful shiny tile. The waves had drip marks where it had stripped off the finish of the tile. I looked for an easy escape out of the house as I knew I'd clearly big time screwed up! It was hideous and I ran to the homeowner to apologize. Of course she'd wondered what the heck had happened. Gracious angel that she is, told me everything is okay...it's not, but i feel guilty. Everything I've tried to make it better has failed. I'm embarrassed and I know partly my fault (directions are on there for a reason!) Make sure you read those before using it on your beautiful tile. I still haven't read them because as soon as I got home after seeing that shower, I cussed that bottle all the way to the trash! Not the end of the world, 1st world issues, whatever you want to call it, just be more cautious than I was, please!

This may be a good product, but the listing didn't state that it couldn't be used on marble floors. Well, guess what? Thats what I bought it for. Then its non-returnable. So, it may be a great product but do some research before purchasing.

This product worked fast and efficiently. My grout is finally white. Inexpensive way to clean grout quickly. The top has a hole for easy administration. I used an ergo grout brush lightly. It does leave a residue so I had to mop with a detergent afterwards but well worth it. The floor looks great.
