This is great stuff, it did an excellent job cleaning a toilette bowl, it eliminated a lot of work with a pumice stone and a lot of other chemicals

This cleaner worked as advertised. I selected it because it was compatible with the Miracle Sealants 501 Impregnator Sealer. It called for an 'acid based' cleaner. Other tile/grout cleaners were "alkaline based". I did also follow the directions to rinse with a solution that will neutralize the acid after the cleaning is complete. I used some baking soda mixed with water and a cloth, then rinsed any residue off with a final clean water rinse.

I used this to clean the efflorescence off of my patio pavers. I didn't read the instructions properly and poured it onto my pavers and it stained a bit. I recommend following the instructions and applying correctly. I also put some in my pressure washer tank so it did remove most of the efflorescence that want I just recommend doing it properly per the instructions as the acid is very strong.

Used black grout on dark tile. This product took care of the haze easily, and after soaking would help dissolve excess grout. Still need a bit of elbow grease!

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.

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.
