GROUT CLEANER & BRIGHTENER

This is an acid cleaner. I didn't realize that when I purchased it. So I had to run to the store to get heavy gloves. It doesn't foam or bubble like in the video, but let it sit and use a brush before wiping it up. It's colorless but smells acidic. After contact with the grout it turned brown as it exacted the dirt. Then watch what a beautiful job it does. It cleans better than any grout cleaner I've ever used before. Moderate ease of use. Just pour into the grout lines. Let sit maybe a minute. If you brush lightly you'll get better results than if you just wipe it off. Finally rinse it off or wipe down with a wet rag. Very good product it works. Note of caution, Wear heavy rubber gloves rated for acid. Also be very careful about kneeling while using. I was wearing old jeans and scrubbing while on my hands and knees. I must have knelt in it. Didn't damage my jeans, but the skin on my knees peeled later that night. Like a bad sunburn. I will wear rubber knee pads next time.

Excellent product for the dirty "white" grout. I've used another product before, and Zep is 100% better. I have a before and after of my floors. It is a lot of work cleaning grout, as for me, I do only a section at a time.

I was honestly shocked at how well the Zep Grout Cleaner and Brightener worked. My tile floors had years of built-up grime and dull, dingy grout that I could never get truly clean, no matter what I tried. One application of this cleaner and the difference was immediate. The formula starts working fast — you can literally see the grout brightening as you scrub. I used a stiff brush, let it sit for a minute or two, and the stains lifted right out. Even the older, darker areas that I thought were permanent came back to life. The 32-oz bottle is a good size too; a little goes a long way. There’s no harsh chemical smell, and it rinses off easily without leaving residue. If you’re tired of scrubbing your floors with no results, this is absolutely worth it. My grout looks almost brand new again, and I wish I had bought this sooner.

This really works. I have white grout on my tile floors and their were getting "off" colored. I used a Q-tip to apply this from a small disposable cup. It was a little time consuming but it worked great. My grout looks new and it didn't damage my tile at all. I am very sensitive to the fumes/smell of cleaners and this one was not bothersome at all. I did turn the bathroom fan on (just in case) but I was happy that it didn't give me a headache. The only reason I took off a star is that If they could make two changes it would be amazing. 1) make it thicker and 2) add a narrow spout or brush o it can be applied directly (without using a Q-Tip)

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.

This stuff is great!! I don't know how anyone could give it a bad review. I let it sit on the grout for a couple minutes and used a hard brush to scrub it and then wiped it. My 20 year old tile (grout) looks brand new. There were a couple 'trouble spots' that needed a 2nd go over but it worked great. Highly recommend!!

I like zep products however this one does not work very well.

This formula is great! The change is visible after the first use, it doesn't smell bad, but wear gloves to prevent any reaction. I've been using it for over 2 months now and my door glasses no longer have limescale. The size is perfect and it lasts for 2 months, It works on marble, glass and metal.It's not greasy and is easy and safe to use as a cleaner.
