Rated 5.0 out of 5.0 acid is acid.. but the concentration is the difference
Acid is acid but if you're looking at the reviews, chances are you're like me and are wondering how strong it really is. Nowhere on the label of this product does it list the percentage of acid, which is odd. I did some digging around and found an old label of the same product that had the information.. and judging by how much it took to lower the Ph in the pool.. it's accurate. This product is 20% hydrochloric acid, which is 13 degrees baume. Standard muriatic acid for about the same price is 31.45% and 20 degrees baume. So it comes down to preference in strength. It's lighter concentration for those like me who get a bit freaked out working with strong acid near the pool.. especially if you've ever been hit with the fumes of regular acid.

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 JR great concrete cleaner
I needed something to clean stains (mostly mold, I guess) off my concrete front porch. I first purchased a "normal" concrete cleaner, but after multiple applications there continued to be stubborn stains. The muriatic acid took them off in one easy 5-minute application with no scrubbing.

Used this prosuct on recmemdation to clean a stain on cement but it didn't work.
It has other uses so it wasn't a complete waste of time.

Rated 3.0 out of 5.0 by gworrel Good and safe, but weaker acid than the strong stuff
When I picked this up at the store, I assumed this was 30% muriatic acid. It is not. This would be fine if you are diluting it, but I had previously used some 20% acid and found it too weak to do what I needed it to do (pool cleaning prior to paint). Nowhere on the container does it list the concentration. I had to come here to find out after I noticed it was not doing the job I expected. This is great if it will work for you because the fumes of standard muriatic acid require a respirator designed for acid. You probably still need one for this stuff but it doesn't generate fumes nearly as much.

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!!!

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 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!
