ACIDMagic Muriatic Replacement Acid for High-Efficiency Cleaning - Ideal for Pools and Concrete - 1-Gallon, 4-Pack Low Fume, Safe Handling - USA128-1

not as toxic as muriatic acid itself and works well

Safer than 31 Baum muriatic acid that I’ve used before. No fumes. Easy to use. Effective pH control for my pool.

We purchased this product to keep our pool healthy and clean. The packaging is very good and delivered in good condition unlike others where the box had been tossed around causing some of the gallons to split open. Will continue to purchase from this company

Overall, I really like this product. It does remove the hard water on windows, however, you’ve got to be careful when using it and wear mask. That’s the only reason I don’t have a five star Ford is that I don’t like that these chemicals could potentially impact the health of my employees, and so we Want to use these carefully. Some ways you can do this on a window is, you can actually spray it on the window from a distance, and then use a pole with a mop to scrub it in if you don’t want to get in the spray zone where the smell is and breathing the chemicals. It is definitely a good product though and is strong and does the job. I’d also recommend wearing gloves to protect your hands.

I feel much more comfortable working with this product than I do working with muriatic acid because of the potential of getting burnt from the muriatic acid. I usually use gloves with working with the pool chemicals but if I just need to lower the alkalinity, I won't put on a pair of gloves, I'll just fill a bucket with pool water, put in the dose of Acid Magic, stir up the contents in the bucket, then distribute in the deep end of the pool. I save a set of nitrile gloves and I feel safe while adjusting the alkalinity. So glad they sell this in the 4 gallon pack. One set of these lasts me through one entire pool season including the opening for next year.

Use it for Ph control in my pool, and cleaning salt cell. Way less fumes. I wear rubber gloves and eye protection , but there was a U tube video a couple yrs ago where a guy was cleaning his empty pool, walls and floor. He was using a bucket with a magic acid solution running hose water and walking around in it with bare feet and shorts, I wouldn't try it but I was impressed.

Works as advertised.

Doesn't work super well. Or maybe the stains I had were just too deep. I had to do get another brand of acid to finish the job. However, the smell was way less intense than the other brand I used. Magic acid also was safer for amateur/diy use. I would buy again for light clean up.
