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

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.

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.

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.

Cut through grout dirt instantly I used it on my old grout stain in my kitchen and ripped up years of actual built up mold inside the crevices. The only thing I could say is that I wish you had a spray. I just reused standard spray from an old bottle to be able to use it for this one. It doesn’t make sense why they don’t give you spray for it because the expect you dump the liquid, from the bottle itself inside the crevices, but that’s painstaking if you have to do a big massive area. This is the reason I gave it a four out of five. But the product itself is actually way above five quality level. I just wish it came with a spray. Pretty easy to use just dump it in the middle of the crevices. Let it sit there for a couple seconds and it dissolves everything. Works perfectly and worth the money. Before using this, I was actually using bleach which was problematic in cleaning up. Definitely buying more when needed. I have a lot of large to medium kitchen and I still have the bottle left. Good enough for a secondary treatment.

This product cleans, grout better than renting a steam cleaner to do it with. It cleans quickly and does not require a lot of hard work or heavy brush scrubbing. A little goes a long way. I was a bit nervous about using it the first time because of all the warnings on the label, but don’t let that intimidate you. It does not splatter or splash, and is easy to direct onto the grout with the small hole in the bottle opening. This stuff is great. See my before and after puctures to see the difference in my grout color. (The tile color looks different only because of different types of lighting in two different rooms. My grout went from almost black back to its original tan color.)

I never write reviews but this product is amazing! As soon as it hit the grout it turned white. Barely scrubbed at all with the grout brush. I used a small rug shampoo machine to suck up the liquid. Then I wet mopped the floor twice just to be sure I got up all of the cleaning solution because we walk bare foot on the floor. Would highly recommend!

I have a before and after! Tell me what you think. I see some difference but not what I was expecting.

It worked OK, but did not clean completely. Make sure you put the bottle on something so none of the product gets on any other surface. It caused multiple dull marks on my laminate countertop.
