Rated 5.0 out of 5.0 by gfphoto Alloy rim cleaner
I have a 1999 Miata and I hadn't been able to clean the stock alloy rims with a variety of cleaners and methods. I diluted the muriatic acid with water and (with rubber gloves and eye protection and outdoors) just wiped it on repeatedly and it started taking off the discoloration almost immediately. The picture shows a cleaned section at the bottom. This was after they had been cleaned with soap and water. I used baking soda in water to neutralize the acid and rinsed thoroughly with water.

Rated 5.0 out of 5.0 by lken Works excellent to remove construction mortar/cement stains
This is my first review on Home Depot web site because I cannot agree with other reviewer's rating. As a home owner, I have done DIY projects such as building retaining wall and using 6x8x16 concrete block to build stairs. I have found that after these DIY constructions, my patio is left with grey mortar/cement stains. The bricks become grey. Regular cleaners cannot clean it. Last night, I tried this safer acid, Followed the dilution instruction, sprayed the diluted over the bricks. Waited few minutes and light brushed and rinsed off. After the surface is dry, the grey is gone and the original brick color is back!!!

Rated 2.0 out of 5.0 by jbagel2 Very weak acid.
It doesn't say anywhere on the container what the actual acid content % is. Which would be helpful. if you just looking for a concrete cleaner. This would probably work. But for PCB etching... It to weak. The Other Blue Competitor, carries the high concentration Muriatic acid that works much better. Just frustrated it didn't list the concentration % on the bottle.

We like to pick this stuff up for our pool when we're low and delivery will take too long from the pool supplier. It's pretty good quality for the price and gets the job done. Not as strong as the muriatic acid we get from the pool supplier thhough.

Rated 5.0 out of 5.0 by stickin2j Did what I needed it to do
I purchased this to get some very major hard-water buildup off an old toilet. It took a few doses, but worked extremely well. Better than any cleaning product I tried, and with far less fumes.

Rated 5.0 out of 5.0 by filmmonkey cleaned up 40 year old stonework around fireplace. didn't hurt me or surrounding decor
I was recommended to use muriatic acid to clean off 40 years of soot and dirt from stonework in my house (around the fireplace). I was VERY worried about the idea of using acid, both in terms of hurting myself and damaging the house. I bought this because it looked reasonably safe. I took regular precautions (wore regular rubber gloves) and probably ended up dripping some on myself because a lot of the time I was working with my arms extended above me, so it ran down. The result was I didn't get hurt, and it did clean the stone up nicely. Not sure how much of that was the scrubbing action and how much was the acid (ie how clean would it have been if I'd just used water), but I felt like I was only going to do this job once, so may as well buy and use the proper stuff.

Rated 5.0 out of 5.0 by bruddah808 Great stuff for cleaning concrete and tile
Needed to clean a locker room floor that was a concrete pad in the locker room and tile in the bathroom area. We had a professional come and clean it with a machine and it still looked bad. This professional told us that it will never get cleaner!
I got the muriatic acid and scrubbed the tile floors and tile walls. It was spotless and shiny after I scrub it down with the product. Be careful as it is very toxic and corrosive! After cleaning, I put a gloss coat on the tile floor. That Professional was amazed!

I buy hydrochloric acid (AKA "muriatic acid") to etch copper from printed circuit boards. I had hoped that this product would be the usual 10M (~31%) concentration of HCl, but it is very dilute. The MSDS quotes a concentration of "<25%." This puts the concentration at somewhere around 7.5M. While it does work, it is much slower than if it were of a proper concentration. I wish companies would stop trying to sell us "safer" products that do not work as well.
