Deck, Crystals, Metal Cleaning- Rust Removal, Wood Stain Remover and More! - Image 1](https://m.media-amazon.com/images/I/71oAi3ZEwzL.jpg) ## 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 ### ⭐⭐⭐⭐⭐ Good price *by P***E on 29 September 2025* ### ⭐⭐⭐⭐⭐ Rustaid Shame On You, This Product WORKS THE SAME!!! *by M***E on 25 December 2023* ### ⭐⭐⭐⭐⭐ It is good for my job. *by J***E on 28 April 2025* ## Frequently Bought Together - OXALIC Acid 99.6% 5 Lb.
