This product allowed me to clean my floor tile grout effortlessly. In some areas, the cleaner stripped off the sealer on the grout because I reapplied and left it on too long.
We were impressed!! Now beware and do not make the mistake we did (and this is our error, not the product) you have to be careful it does not splash onto other surfaces. For the most part we caught it but a small amount splashed on the bottom of our nice new fridge and it discolored it - this stuff is strong!!
I bought a 1930 house with original white hexagonal tile floor in the bathroom. The grout was black. I did multiple applications of this product, and I was able to get the grout to white or light gray. It's a huge improvement.
disappointed in this product. it did not work at all for the white grout in my bathroom. And it was extremely messy. Plus, there were so many warnings on the bottle about it's toxicity. You have to be in a ventilated area, wear safety glasses and gloves. So I did all of this, followed the directions exactly and my grout is still stained.
The brush was too rough and the product didn't really penetrate as well as I hoped, leaving a totally uneven and frankly still dingy look. Day two I got smart after watching some how to videos on Youtube and bought some Oxyclean at Walgreens for about $8 for a large tub.
I just moved into my house 2 weeks ago. I moved some appliances and realized the grout needed to be cleaned. I tried MANY different products and concoctions. I finally stumbled upon Zep on Pinterest. If I could give this product 10 stars I would. It's unbelievable!
I bought this product because the reviews looked good. I use it with my orek oribiter and was not super impresse. The cleaning product I had gotten from the dollar store worked just as good. You also have to rinse this off really good because it leaves your grout and floor sticky. I would try something a little cheapier.
Ok, so I give this product high marks because I found a way for it to work wonders, but not using this product by itself. I'm going to tell you the method I used to clean my kitchen floor on a 12 year old house with original tile that may very well never have been cleaned. This took me three days to complete to my satisfaction.
