Miracle Sealants Heavy-Duty Acidic Cleaner, Quart, 6-Pack

This works where CLR doesn’t.

This is a very good product for bathrooms where it's difficult to remove hard, stone-like toilet bowl cleaners. This product makes them disappear. I work doing deep cleaning, and believe me, it has helped me a lot. I recommend it and certify that it delivers on its promises.

Was using it to get the dust from grout off the stone but it's very stubborn. The first wash took off most of it but needed another session. Will probably need to order another bottle for another go at it to get the remainder. It's strong stuff though.

I used this on my cement front porch before painting, and after more than 8 months there’s been no peeling at all. The cleaner worked really well at removing old residue and getting the surface ready. It made a big difference in how well the paint stuck. Great product for prepping concrete or stone before painting or sealing!

I guess it helped some, but i certainly wouldn't call it impressive. I wouldn't buy this again.

This product had absolutely no effect on my problem. I'm extremely disappointed considering how hazardous the product is and how much effort the manufacturer demands for proper handling and use. I am working on reclaimed granite from the local stone yard. The granite shows various imperfections from its previous use: lots of old mortar, both sanded and unsanded, as well as discoloration due to unknown causes. Although having followed the tedious instructions to the letter, I am sorry to report the net effect on the granite's appearance was zero.

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.

EXCELLENT - MIRACLE WORKER!!

Good product, recommend

This product is bought for cleaning granite,stone & tiles.....stain remains the same on suface...any ordinary surface cleaner solve the purpose.
