I am trying to remove efflorescence from our slate tile and marble tile grout lines in the shower. Is this product safe for use around those stones or is there another product that you can recommend?

Answer: 
TileLab Sulfamic Acid Cleaner is not recommended to be used on Marble tile. Aqua Mix NanoScrub Abrasive Cream Cleaner would be the appropriate product for removing efflorescence in an acid-sensitive installation.

Although the Sulfamic Acid cleaner is a mild acid, i would not recommend it coming in contact with the wooden vanity, radiator or the toilet seat. If the tub is anything other than porcelain i would not recommend it come in contact with that either.

Answer: 
You should cover everything as a precaution. I always do. Better safe than sorry, as they say. They do say that it should not come in contact with metal, which would prob. mean your radiator. I was looking for an answer to another question, but when I saw yours, I wanted to say, I don't think this product is meant for natural stone (which mosaics are generally made of).

Everything I have read says that it will possibly etch the stone. Google it and you'll see many references to that. We just put in a travertine shower floor, and I saw that caution frequently. For what it's worth, a lot of mosaics happen to be made from travertine . . . Read Less

I used this on the grout next to porcelan tiles

because I couldn't get the haze off the grout. But now I have streak marks on the tiles next to the grout...have I ruined my tiles?
I followed directions by rinsing off the areas in which it was used, and yesterday morning, I steam mopped to see if that would remove the streaks, but it did not.
Help! :-)

The lesson here is to make sure you rinse the sulfamic acid really well when using! Then you won't have to do the extra work that I did. :-)

Will This Effectively Remove Grout Haze/Residue From Wood Grain Plank Tile?

This question is from TileLab 1 lb. Sulfamic Acid Cleaner
Asked by
Winston Salem, NC
Read all my Q&A
January 13, 2015
I am laying wood plank tile with a fairly heavy grain pattern. I am concerned about the grout getting into the "wood grain". Will this product remove the grout from those "wood grains" without damaging the grout between the tiles?

As info, this will be a small area of tile, so I am using a premixed sanded grout.

Answer: 
Yes it will. As long as you sponge frequently while grouting, you won't even need this.

Answer: 
Sulfamic Acid Cleaner helps on the removal of cement grout haze from ceramic and porcelain tiles. If you are using a premixed grout then a different cleaner should be used, such as TileLab Heavy Duty Stripper & Cleaner. Check with the wood plank tile manufacturer for approved cleaners.

Rated 4.2 out of 5 by 48 reviewers.
Rated 4.0 out of 5.0 by It worked...with work. The product did the job (THAKNFULLY). It requires a significant amount of elbow grease. The label suggested 8 oz to 1 gallon of water. WELL, I gradually increased the amount to ultimately require the entire jug in 1 gallon of water. With lots of scrubbing, and leaving the product on for 30 minutes, I got the results I wanted. Note to DIY-ers, seal the natural stone before grouting. I should have re-read the grout container a few more times... WHOOPS January 28, 2016
Rated 4.0 out of 5.0 by Does the job Did a nice job of removing excess grout and this set. It still takes a little hand scrubbing, I used non abrasive pad. You will alos need gloves, its strong stuff. Gives off a sulfur smell, so ventilate. July 5, 2016
Rated 5.0 out of 5.0 by Awesome stuff We had laid tile in 2 bathrooms and grouted them. The grout was a medium gray color. When it dried it had a white film on it we tried everything. I finally called Mapei the grout maker and asked what to do. They suggested the Sulffmic Acid Crystals and a stiff bristled nylon brush. So off to Home Depot I went. I used one 6oz. tub with one gallon of hot, hot water. I scrubbed each grout seam with this stuff and wiped it back down with plain water. My tile now looks great. June 14, 2016
Rated 1.0 out of 5.0 by Did nothing for grout efflorescence Tried this after my CBP Bone grout dried white. Maybe it was too much water, maybe it was a little too uniformly white to buy that. CBP suggested I try this. Mixed in the amounts specified on the container, scrubbed vigorously as suggested....and sorry, it didn't do a darn thing. Not happy about it. But at least the white isn't as ridiculous from bone color as it would be from a dark color. Very disappointed in CBP grout though and this product did nothing but cost me more money for an inferior look. May 14, 2016
Rated 4.0 out of 5.0 by Works well, but experiment with it This product does what it says it will do, but I wasn't prepared for it to stain the grout between the tiles, even though I used grout sealer. May 17, 2016
Rated 5.0 out of 5.0 by Great with Polyblend Grout Renew Used Sulfamic Acid Cleaner as specified with warm water - 8 oz. mix for light mineral deposits. It wasn't a fun process, but it removed built up grime and allowed for great coverage with Polyblend Grout Renew. Thrilled with the results. March 19, 2016
Rated 5.0 out of 5.0 by Awesome product! Great for cleanning the shadow that leaves the grout on the tile!! Works great just follow the instructions given directly by the company in the Q y A section. 1gal of warm water for 8-12 grams of the product. Apply with a regular nylon brush in circles and then rinse with water!! You will get great results!! March 16, 2016
Rated 4.0 out of 5.0 by It works on whitened grout, BUT... This works to remove the whitish substance left on dark grout when you use too much water. HOWEVER, it WILL NOT work if mixed in the proportions suggested on the container. I first mixed with water per the instructions, scrubbed the solution into the grout with a toothbrush then wiped with a wet rag. The result was a slightly better appearance, but not by much. I then dumped most of the remaining product into the solution, brushed the solution directly on the dry grout and let it stand for about 5 minutes or so before wiping with a wet rag. Guess what - it worked! A few places needed a second treatment, but for the most part it looked great. December 11, 2015
