## Questions & Answers

**Q: How much powder is used per gallon of water?**
A: For comparison, the commercial product Goof Off Rust and Stain Remover, according to its MSDS, contains 10% oxalic acid so I would start with a 10% -12% solution (~0.8 -1 lb in 1 gal, 8.3 lbs water); and if that does not work increase the concentration in 10% increments.

**Q: how soon can a pet walk on the deck after using?**
A: Depends on how much you love them, I guess.

Actually, it should be okay after a good thorough rinsing. Don't let them drink any puddled water, though. It usually degrades in the environment in less than a day.

**Q: Is this product Oxalic Acid Dihydrate?**
A: You would have to call Florida Laboratories Inc. and ask them, as their packaging only shows the product as Oxalic Acid 99.6%.  www.flalab.com

**Q: Will this acid clean rust stains from well water iron on my driveway?**
A: use of Oxalic acid for rust removal on driveways

## Customer Reviews

### ⭐⭐⭐⭐⭐ Recommended
*by C***S on July 18, 2025*

Easy to use. Typical purity. Good quality.Normal appearance. will buy again.

### ⭐⭐⭐⭐⭐ Use it cautiously
*by A***R on August 6, 2024*

This is something that will clean toilet tanks and bowls but use it cautiously and with gloves. It is very corrosive to skin. I use it as if it's comet. Turn off the water, flush and then scrub the bowl and tank Turn water back on, Let the tank soak abt 20 mins and flush a few times. You can get water spots of glass with this too and clean showers (porcelein) and tubs. I wouldn't use it on fiberglass or other similar products.
