    Really does clean off grout

    Posted by Doug on Dec 30, 2022

    While grouting my shower surround, the grout set up crazy fast before I had a chance to fully wipe down the tile. I scrubbed and scrubbed, but as the day went on, it became obvious it was useless. I was resigned to having to rip the tile out and start over - it looked BAD. After Googling, my wife suggest we try vinegar - and to my surprise, it actually worked pretty well! I then got a bottle of this to try. Gotta be honest - there is NO way you are going to get yourself out of this situation without a lot of elbow-grease - but this cleaner really did dissolve the hardened grout and saved my tile project! It took a couple of applications, and a few Scotch-Brite pads, and a couple of beers, but now my tile looks great. Whew!

    We have used this product before and found it to be the only product that will remove water deposit whitish stains on tile and steps that come from the pavers after a rain.
