SUNNYSIDE CORPORATION 71032 1-Quart Muriatic Acid

I've been trying to find something to clean the rust stains on my Bluestone steps for a while now and finally this did the trick! You may have to alter the proportions recommended on the bottle as I needed more potency in the mix to get out the truly stubborn stains. However, the steps look new. I would just caution that you should wear a mask that protects against fumes, similar to using any solvent or acid, as if you increase the potency of the mixture, additional fumes will be generated. Otherwise great solution for a great price as some major brands sell "masonry stain removers" for an expensive price point and none of them worked, believe me I tried them all.

I needed to clean the frit of my Buchner filter and after researching decided on muriatic acid, as recommended.. This acid is of good quality and cleaned the minerals out nicely.. It is also not too strong to easily neutralize when the process was complete. Thank you very much,

Perfect for my 3000 gallon pool. I didn’t want to store a gallon of this so to find a small amount was great. Works well

Came 2 days early exactly what i needed....Just remember the product name and ounces and your order should b perfect....Big kiss out to all

i use this either alone or in combination with some other chemicals to produce a patina on artwork. Strong stuff - I like that - and you don't need much to get what I need. Super careful around in regards to the fumes etc. This should last awhile for me.

I bought this muriatic acid after seeing a TikTok trend about bleaching seashells — and yes, it definitely works! The shells came out looking great. But be warned: this stuff is no joke. The fumes are incredibly strong, so make sure you wear gloves, work outside or in a very well-ventilated area, and cover your nose and mouth. Also, don’t use any bowls or containers you care about — they’ll be ruined. It does the job, but absolutely respect the strength of this product.
