Customer Reviews for ZEP 32 fl. oz. Grout Cleaner and Brightener

After many cleaning products and home remedy solutions I was just about ready to call a professional company to remove my shower grout. After doing a bit more research I came across this product and couldn’t be more pleased. Worked amazingly! Make sure you follow instructions and I recommend wearing gloves, long sleeves and pants and ventilate the area. Strong smell but nothing unbearable. And get a good grout brush!

Product does what it claims. 20 years of dirt in grout wages away with no effort. Product really works. Use in ventilated area or a fan it is pretty strong.

I followed directions to the tee… did nothing for the grout…

My friend recommended me this product that she saw online. I bought it and tried it on dirt on grout that would not come off for years and in 10 mins my grout is visible. I love this product

Highly recommend! We moved to a house where the grout was pretty dirty and gave this a try. Amazing results and only took a few minutes.

We have a fully renovated house - when renovating we had builder do the basement in full ceramic tile. We loved the tile but hated the way the gout looked. Light grey/white in some places and in others it was stained with sawdust and red Georgia clay. No matter what I tried (abrasive cleaners, steam cleaners, steam mop, scrubbers attached to a drill with bleach - nothing would remove those dirty red stains. This stuff is amazing. this stuff is amazing. So glad I tried it.

Bought this to see if it worked I didn’t know how dirty it was I’m impressed love it.

I’ve never felt so compelled to write a review! I moved into a 112 year old house this summer that had some of the grossest grout I’ve ever seen in the bathroom. I tried bleach, the blue toilet cleaner trick that’s viral on tiktok, and even steam. Nothing cut through this dirt. I decided to give this grout brightener a shot and within 5 minutes, it looked like brand new tile! I’m so impressed. I will be recommending this product to everyone I know.

So read the bottle. Be sure to apply this and brush it into the grout. Then let it sit. But this grout was old and crusty. The pics say it all

My grout was one and old like other pics. It did lift a good amount of dirt and it looks better but it’s not sparkling white. And then I feel like I cleaned it like 3 times and used my steam mop. First time I just let it sit. Ye read the directions. Apply it and brush it then, wait 3 minutes. Still gonna need something else to get it white white. It’s just like beige now. So adjust expectations folks.

I used this on some tile in the kitchen in front of the stove, which had gotten pretty nasty. I was very surprised at how well it worked. I had scrubbed the heck out of that grout with bleach powder with no luck, and this cleaned them up pretty much instantly.

This product did not disappoint! Would definitely recommend.

I applied cleaner properly, waiting for 5 min after application and then scrubbed hard with a hard bristle brush. I did this twice. The result was no different from another section where I did one application with Vim cleaner and a cloth. It cleaned it OK but I expected a much better result with the Zep in restoring the original white colour. Unless your only interest is the cleaning and not colour-brightening, then I do NOT recommend.

This product did clean my 20 year old tile and grout floor. It almost looks new again. Very happy with the product.

I never write reviews but I had to for this product. Sprayed on and 15 minutes grout all cleaned! I’ve attached before and after pics. No comments please about how dirty it was lol

As a renter for the last 4 years in the NYC area I can say this is the best product I have tried yet for cleaning floor grout. I was trying every DIY method I could find on Pinterest and stumbled upon this and it is way easier and less clean up. The only downside is the smell- definitely ran a fan when using and steam mopped after wiping grout clean to remove any remaining product.

I was a little disappointed with how this worked. I saw reviews for it all over the internet, showing how well it worked without any scrubbing. Lucky i bought a grout scrub brush because it definitely needed to be scrubbed to get clean. It's still worth getting to get grout clean, just not as amazing as it's made out to be.

After using this product on my tile floor, It discolored the tile leaving it white and visibly noticeable with a harsh dull appearance and touch. Could this product have ruin my floor? Not ha

Purchased this home last year. I don't think this grout has ever been cleaned. Works amazingly well with very little effort.

Follow the directions. I let it sit for 3 to 4 minutes. I brushed with a grout brush. I might as well have been using plain water.

Buy it! It works! It is easy! I thought my grout was brown and then I used this and found a beautiful, almost white color.

I’ve tried a lot of products but will only be buying this from now on

Our grout had 20 years of dirt and grime. After reading reviews and comparing other products, I decided to try this. I was amazed with the results. It was quick and easy to use. I really wish I could have added more photos. My tile and grout look new. We also purchased a brush to use with a drill that was so worth the money. I would definitely recommend this product and hope you receive the same results we did.

Wow! I cannot express enough how much I love this product. I used it to clean white grout between white tile and it literally lifted all of the dirt and grime up like magic! I just had to lightly scrub it with a brush and then mop. So easy!

I was skeptical about the product at first. It works better then expected. I let it soak for 3 minutes and agitate it with a brush. Then clean it with a wet rag. I highly recommend it.

This cleaner did a great job on my tile. Used this in addition to my steam cleaner. A little elbow work but saved myself some money.

Works great. Floors look like new

Easy to use and very effective but the chemical nature of the product is a little alarming. Definitely use gloves and glasses as recommended on the bottle.

Not much scrubbing and grout was looking brand new!

The grout in a home I just purchased was filthy. I wouldn't have walked on it with someone else's feet. I read about Zep and have it a try. Five bottles later, I can say it works. It didn't get the grout back white but it surely got it close. If it had restored it to its original color, I would have given it 5 stars without any hesitation. I recommend it if you don't mind adding a little elbow grease.
