Kitchen countertop tiles

Is this product safe to use on Kitchen countertop tile grout?
Asked by: emily
Hi Emily, grout is grout. Just be sure to sponge it off the tile with water after you have cleaned the grout.

Can it be used on grout on walls of shower. Descriptions says no-earlier reply says yes. Does this mean shower tile walls? Why or why not?

Asked by: SKinreho
On the floors you kind of squirt it on and you're supposed to let it sit for a few minutes. I imagine that'd be a little difficult on a wall but you could give it a shot. The liquid has the consistency of water, not very thick so it would run pretty quickly. May not provide as effective results as it would on the floor, but it should help.

32 fl. oz. Grout Cleaner and Whitener is rated 4.4 out of 5 by 266.
Rated 5 out of 5 by from Works wonders My floors were embarrasingly disgusting, the white grout was black in some places and the tiles had a dirt film over it that wouldn't come off no matter how much I mopped. I decided to try this grout cleaner because of the reviews and I am glad I did. It was a lot of work that was back breaking but now I just stare at my floors because they came out so great. I used a grout brush for the grout itself and a hand bristle brush to scrub the tiles, two buckets, one for clean water and one to rinse the brushes off in. My husband had knee pads which saved my knees so I'd definitely recommend those as well. It's the most cost effective and best way to get your floors shining again.

Rated 5 out of 5 by from This stuff is GREAT! I used to use comet or bleach and it was a stinky smelly mess that left a lot of residue behind (from anything I used that had an abrasive ingredient in it). This stuff is so easy to use with no overpowering smell. I did transfer it to a small bottle that had a long nozzle on it (recycled from a hair dye package) which made it super easy to apply a thin line to just the grout line. Left it set for about 10 minutes and then scrubbed lightly with a grout brush and dirt was gone! Just wiped down with my usual floor cleaner in a bucket with a rag and I was done. This will be my go to grout cleaner for that 2x a year job that I always procrastinated on. And the price is reasonable too!

Rated 5 out of 5 by from Best grout cleaner I've ever purchased It's very rare that I say this, but: this product is UNDERPRICED. For the price I paid for it, I expected mediocre results. I was amazed at how clean this made my grout. Use it as the label recommends and you won't be disappointed. Yes, it does require scrubbing with a brush, but not much. The acid does most of the work; you just have to use the brush to get the crud out so you can wipe it away with a sponge. As for the fumes: I'm asthmatic, but I didn't have to wear a mask. I just kept a fan blowing across the floor while I worked. Can't recommend this product enough. And, as someone else mentioned: you won't see the final results until it has completely dried.

Rated 5 out of 5 by from I don't typically review products but in this case I thought differently. This stuff really works... I don't typically review products but in this case I thought differently. This stuff really works. It is quick, easy to work with, cheap and the results are impressive. My grout lines look like the day they were new, this after 12 years of heavy traffic, dirt and grime. Two teenagers who typically don't notice much even commented that the floors looked great. At least in my area Home Depot the product was not in the tile section but rather in the cleaning materials isle. It is worth looking for.

Rated 5 out of 5 by from This grout cleaner really works! I just bought a second bottle. We bought a house a few months ago and the grout was awful. I wasn't sure we could get it white again. I got a grout brush for about $8 and put it on the end of a pole and used it with this cleaner and it worked great. I had to do a few areas a second time. The smell is bad but I have a sensitivity to smells and was able to tolerate it so it's not as bad as the perfume many people wear. The picture shows an area I did next to the area not done in the laundry room.

Rated 5 out of 5 by from Best best best This stuff is the easiest to use and work great! I have a pet-sitting business so I have lots of pet traffic in my house and quite a few accidents. The grout in my house was super dark and to be honest, I just thought it was that color. I bought this stuff and it's not dark grout! It's so easy to use as well. You techinically don't have to scrub to get it clean but it comes out looking better for you scrub it. Let it sit for a minute or two and the grout cleans right up!!

Rated 5 out of 5 by from Best grout cleanng product We have a black haired dog and with time, her oils got into the grout and it got darker and dull looking. I kept washing the floors it seems the grout only became worse. Then I tried many grout cleaning products from natural with baking soda to heavy duty ones... nothing worked. So I was a bit skeptical about this one but honestly this products acts instantly with no scrubbing .. you see the grout change color right away ... it's just amazing !

Rated 4 out of 5 by from Worked better than expected, follow instructions This product does as advertised if you follow the instructions (i.e. work in sections). The attached pic is my very small test area. Once I saw how good it worked, I decided to work in large sections to save time. I probably treated an 8x4 or more section of tiles; basically I split my kitchen into thirds. This was a mistake and I do not recommend this. Zep actually fizzes and lifts the dirt. Therefore, if you don't mop/wipe the dirt away in a timely manner it will resettled in the grout lines. So work in small sections. I recommend 2x2 or 3x3 sections. That's 4 or 9 tiles for those not good in math, lol. Also, I do recommend using a grout brush for more difficult areas.
