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!!!
This is a product that should be used carefully. Always be clear what you are doing and in what order. Always have all safety equipment. I have seen people be casual with this chemical and not wear proper gear or precautions. Usually they get away with it but that just encourages them to be stupid next time too, and it catches up with them. Sometimes I have been there with a ready garden hose. I haven't seen anyone get a burn on their face or eyes and I hope I never do. That said, this particular acid comes in a bottle that didn't drip or leak. It is not as yellow as some which could mean it has fewer impurities, not that is good or bad. While those features don't sound like high praise, maybe they are. That is about all a manufacturer can do to keep you safe and for the product to perform. The rest is all up to the user. If you are not experienced, do this with an experienced person. Never work with acids alone. There should be someone as a buddy to rescue you if something goes wrong.
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.
This product is more expensive than traditional muriatic acid and it is weaker than the muriatic acid sold by leading pool supply houses, Gallon to Gallon comparison makes other standard full-strength muriatic acid about 1/3 less in price. Given the additional dilution (less than 25% per MSDS) for this "Greener"...ahem...weaker version it would cost me about double to use this product over the long-time standard typical (31.45% HCL) Muriatic acid.
Home Depot Buyers: Please do a better job.
Cons: does not list concentration of hcl, weaker and more expensive than traditional acid.
I bought this to use in my pool to lower the ph - I thought I was buying the usual strength muriatic acid I have always used...This is NOT it. It is "green" and "safer" as a result be prepared to just buy more. I went to the other national chain store that starts with a "L" and got the normal strength I have bought in the past. This stuff is useless....
The product performed as expected and had much less smell than standard muriatic acid. I would not hesitate to buy the product again. I was surprised/pleased, because my experience with the "green" (reformulated) paint thinner is that it is useless.
Based on the MSDS sheet for this product, the acid has a density of 9.09 pounds/gallon. This equals to about 20% HCl, or 13 Baume. The other "fuming" HCl that is sold is labelled as 20 Baume, which is 32%. So you need to multiply the amount you used to use for the 32% HCl by 1.6 to add the correct amount of acid compared to the more common 20 Baume acid. It works fine in pools, without gassing yourself if the wind changes while mixing.
Old disgusting toilet showed no sign of being able to be cleaned. A little of this plus some elbow grease did the trick. Its diluted enough that you don't feel like you are going to burn the skin off your hand if you accidentally touch it, but strong enough to do the job. Highly recommend it for porcelain (just be careful it doesn't eat away too much of your toilet's wax seal!)

Review 15 for 1-gal. Green Safer Muriatic Acid
Save your $$$
PostedNovember 17, 2011
No, I do not recommend this product.
I got this product to etch and clean my driveway........not worth it at all this product is sooooooo weak and diluted, I think this product is mostly water. It took the whole gallon to clean small area.
I didn't need any where close to full strength, but this stuff was still totally worthless. No apparent acid content, zero power. Zero reaction with water. Put a drop on my hand. Nothing. 3.2 beer has more kick. Seriously, don't waste your money or time.
Pros: won't kill plants?
Cons: a bit expensive for non potable water.

Review 17 for 1-gal. Green Safer Muriatic Acid
The product does what it is supposed to do, disolve morter.
My Mineral Springs salt cell chlorine generator was barely generating free chlorine. The owner's manual recommended cleaning with muriatic acid. I followed all of the safety instructions and cleaned the cell with this acid. Cell is working fine now.
