Zep Inc 32oz Zep Grout Cleaner Zu104632 Kitchen & Bath Cleaner

Excellent product

It works well but ensure you're wearing protective eyewear and plastic gloves.

This grout cleaner is incredible. I actually can't believe how my floors look they look like new. Great stuff!! Potent though I wore a mask.

Well, make sure you wear gloves and glasses. This is really potent stuff! And nothing will clean grout as well.

5 star customer service. Product as advertised

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.

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!

Product is marginal at best, which makes it extremely expensive. Does a reasonable job on tiles but cannot clean grout. In addition, after use, the floor is slippery and it leaves a slippery residue that is difficult to remove. There are many less expensive products that will do the job better.
