Question: What do you apply ZEP grout cleaner with to keep it on the grout alone?
Document: It was cheap and came with a very easy spout so I could easily apply to the grout not making a mess. Now the floors, while not looking brand new mind you look worlds better!
I tried several cleaners before this one and it definitely works best! All you have to do is apply and see instant results. When I get it again I'm going to try to find an applicator squeeze bottle so I can run it right down the grout line. Very little scrubbing required.
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.

I have looked for years for a grout cleaner. Finally I have found it. Put on your grout line let it set for a couple of minutes, i use a toothbrush to scrub a little and rinse, very well. Oh my! I was hating all the tile in my house, but now that I found this grout cleaner, I&#34;m starting to love it again.
I paid a professional tile cleaner to clean our tile/grout in our home. Years of dirt / grime built up in the grout and thought the pros would get it clean. Well, they almost did the job but we had many grout lines still very dirty. Within minutes of applying and lightly scrubbing... this stuff had the grout looking NEW!
yup its grout cleaner. how exciting!! what can i say, it's liquid, it comes in a jug, you put it on your grout, then the wife scrubs the grout, and then I have clean grout. I just couldn't be any happier.... until my grout gets dirty again. Why doesn't someone invent a non-porous grout? then it would come clean when the floor gets washed and you wouldn't need to drop cash on grout cleaner.
It's a very strong chemical, you need to read and follow the directions, of course. But it was pretty simple to use. You squirt it on the grout, and brush the grout a little with a grout brush (to make sure the cleaner goes in the nooks), let it sit for 5 minutes, then rinse with a very wet mop. I am amazed. My kitchen floor grout looks like it did originally! Finally, a grout product that really works!
I have a large, light colored floor with almost white grout, which was darkened in all the high traffic areas. Simply washing the floor does not clean the grout, which is so frustrating, as the floor never looks clean anymore. I've tried a few special products, never heard of Zep until it was mentioned in a review for a steam cleaner. So I decided to try Zep before spending $100 on a steam cleaner.
Not sure what's in this but it didn't do much. No whitening or cleaning after scrubbing with brushes.Ended up using the Zep shower and bath cleaner and it worked like magic. The rest of this will go down the drain..
