Doesn't work on tile or grout, regular use hard water and deposits look no different
I tried this product on my shower tiles and grout, followed the instructions to a tee and even left it on for a few more minutes while keeping it moist and agitating the solution so it didn't dry and it didn't really remove anything other than surface dirt which is not what I purchased this for. And the cap leaks, disappointed :/

5.0 out of 5 stars Worked well on shower tile
Reviewed in the United States on September 7, 2023
Size: 32 Fl Oz (Pack of 1)Verified Purchase
Had a tremendous amount of bar soap build up on the some of my shower tiles. I wet the shower tiles and then splashed some of this directly onto the tile. I used a Rubbermaid firm bristle broom to agitate the tile and then let it sit for the 10 minutes. It worked like a charm and I wish I had found this stuff sooner.

5.0 out of 5 stars It's a MIRACLE!!!
Reviewed in the United States on March 26, 2018
Size: 32 Fl Oz (Pack of 1)Verified Purchase
AMAZING! This stuff is made by a company called "Miracle" because it is a Miracle! I made the mistake of using Irish Spring bar soap for about a year which I now know is the worst soap scum producing soap on the market....the scum on my tile was so bad I could scrape it off with a razorblade and it came off in little rolls like you were shaving butter. It also turned my grout white where it built up on the grout too. I went to Home Depot and bought the AquaMix Heavy Duty Tile/Grout cleaner as well as the Zepp grout cleaner and used those products first which did basically NOTHING to the soap scum. I bought this product here on Amazon (apparently it used to be sold by Home Depot but not anymore) and after two rounds of easy application and scrubbing per the instructions on the bottle my tile and grout looks like brand new again. All the soap buildup is gone! Don't waste your time with any other product!

PS - Make sure you wear old clothes, wear a respirator and a face shield, head cover and goggles when using this stuff, it's nasty!

PSS - I contact Miracle Sealants to ask if it would eat the caulk and they told me they have never seen it damage caulk, which is nice.

5.0 out of 5 stars Good product for the cost
Reviewed in the United States on June 13, 2019
Size: 32 Fl Oz (Pack of 1)Verified Purchase
I had been trying to figure out how to remove some dark scaly substance from the low area where the water exits the toilet. It looked terrible. There was an additional problem in that the flushing action was too slow, leaving waste in the bowl. Not knowing that the two problems were related, I did some googling and found your product. I lowered the water level in the toilet, poured the Heavy Duty Acid Cleaner in and went to bed. When I got up the next morning, I flushed the toilet...lo and behold...it flushed like it should! If that wasn't enough, most of the dark scale was removed also. A little bit of scraping with a wooden stick took care of the rest. Couldn't be happier...and much cheaper than a plumber. I'll buy it again!

DIdn't work that well for me. Tried on three separate brickwork sections with mortar/lime stains. Tied 10:1 and even up to neat in some places. Fizzes yes, but despite leaving 3-5 min and agitating, it is not lifting as well as other products I've used in the past.
