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

Amazing! Worked instantly and after a little scrub it got everything up! So happy with how well it worked. Took my grout from black back to tan. Just make sure to wear gloves and get a little grout brush or toothbrush to scrub the gunk out. Doesn’t smell great, so make sure you have the fan on or good ventilation.

I was genuinely surprised by how well this grout cleaner worked. It removed years of built-up dirt and stains, making my grout look dramatically cleaner and brighter. The difference before and after was easy to see. The formula is powerful, so a little goes a long way. With some light scrubbing, it restored the appearance of my tile much better than other cleaners I've tried. If your grout has become discolored over time, this product is definitely worth trying. It delivers impressive results and made my floors look much newer without the need for expensive professional cleaning.

I’m seriously impressed with Zep Grout Cleaner. Our grout had gotten noticeably dark and dingy over time, and I honestly didn’t realize just how dirty it was until I started cleaning it. The difference was immediate and so satisfying to see. It was easy to use, and with a little scrubbing, the grout looked dramatically lighter and cleaner. The before-and-after difference speaks for itself. This saved me from feeling like I needed to replace or professionally clean the floors. Highly recommend if your grout needs a refresh!

I picked this up after getting tired of looking at the grout in my bathroom—it had gotten pretty dark over time and nothing I tried really helped. I wasn’t expecting miracles, but this actually did a solid job. I applied it, let it sit for a few minutes, and then scrubbed with a brush. You can definitely see a difference after just one pass. It didn’t make everything look brand new, but it got way closer than anything else I’ve used. Fair warning, it’s pretty strong stuff. The smell is noticeable, so I’d crack a window or turn on a fan while using it. I also ended up using gloves just to be safe. That said, it works, so I can’t complain too much. You don’t need to use a ton either, so the bottle should last a while unless you’re doing a huge area. Overall, it’s one of those products that actually does what it says. If your grout is looking rough and you don’t want to replace it, this is definitely worth trying.

So I bought the Zep Grout Cleaner and Brightener. Then I was looking at a YouTube video on how to apply it and they mentioned that they were not satisfied with the results and ended up painting the lines on. I really came close to doing it as I started researching buying some grout paint. Then I changed my mind because I did that 15 years ago and was not happy with the results later. So I proceeded to apply the Zep Grout Cleaner and waited 3 1/2 minutes before scrubbing a 2X2 foot area in my bathroom. It’s not the cleanest it’s ever been, but it’s the cleanest. It’s been in five years. Seven years ago, I removed all the grout and re-grouted the floor and sealed it. The sealant didn’t even last three weeks, before the floor started looking grimy, even after I cleaned it.I was very upset. I have used the peroxide paste before on the floor and the Zep definitely worked better, but because I saw a video today, where a guy was comparing Zep and peroxide for cleaning floors, I actually think the cleaning magic comes from the ITTAR Grout Brush with Long Adjustable Handle, Swivel Scrub Brush, V-Shape Grout Line Scrubber with Stiff Bristle. I actually thought it was just a regular hard fiber bristle brush, on a mop stick and that it was just going to prevent me from bending over. It isn’t a fiber brush; it actuality it is metal bristles with an angle to get deep in the crevice of the grout. Mind you my grout is not bright white and is not perfect, but I no longer feel like I am living with “Sanford and Son”. Definitely get chemical gloves and wear a mask. I splashed some of this on my toilet seat and it ate the paint off of it. Although the stained baseboard, I wiped within seconds after scrubbing, and there was no problem with that or the stain that’s on the bath cabinet. Before applying the Zep, I sprayed Goo Gone on the floor around the toilet and rinsed the floor with water, then let it dry. So the before and after pictures you see, has the first picture with kind of a clean floor, but with zero scrubbing. Then once it dried, I took a picture and then began cleaning with the Zep.

Although this does an excellent job of removing dirt from grout, there are few drawbacks on ceramic floor tile. The item is hard to pour out without getting it on the tile too, and I noticed it stripped the clear finish off the tile where it touched. I didn’t notice it right away, but a few days later, I noticed where the zip set on the tile it was dull and then in the middle of the tile it was shiny. It’s very difficult to apply this without getting some of it on the tile. Like others say the smell is awful. You definitely have to use it when it’s a cool dry day and you can open windows to get rid of the smell. It is an acid so you should protect your skin with gloves and have long pants on. I didn’t wear a face mask, but I did have my windows open and put the exhaust fan on in the kitchen while using this. I’m not sure if I’ll continue to use it only because it took the satin finish off the floor tile so now it has a dull and a shiny ear look on my tile. I guess I could put it on all the tile now and make it all dull finish so it’s even but I’m not sure if I want to do that yet,. I recommend this item with caution. It did make my grout look like it probably was brand new, but wasn’t happy that it told the ceramic tile where it touched. I don’t see how you can apply this and just get it on the grout only. That being said it does what it says. It does definitely removes all the dirt from your grout.

I’ve never used any other brand of grout cleaner before but this has to be the BEST! It works super fast and the bottle is big for the price. My tiles look amazing now and back to the color they were before. The scent is strong but not too bad. Would recommend to anyone!

I am amazed. I never write reviews but felt compelled because how well this product works. your gonna want to buy a standing grout brush to save your back but it doesn’t take too much elbow grease to break up DEEP set in ick. You can tell from this picture which half has gotten clean and which hasn’t. I hate cleaning and I was sucked in because it was SO satisfying how quickly it got the grout clean. 10/10 will buy again.

5 star customer service. Product as advertised

très efficace

I never ever ever write reviews. But I ordered this because people were posting before and after pics and I couldn’t believe it. It was expensive. More than I really wanted to pay but figured if it sucked id return it. BUT OH MY GOD!!!! Don’t judge the gross dirty grout, just bought the house. I used an old toothbrush to get in between the tiles easily. This was superrrrr easy to use. I did my entire kitchen (100sq ft roughly) with half a bottle, but you see in the bottom section of the first picture that my grout was dark grey. And apparently it’s off white. I am beyond satisfied!
