Measurements and Instructions not Included. Review: Perfect for removing water rings when refinishing furniture - I used this in the process of refinishing the top on a Broyhill Brasilia credenza. This was a collectible and desirable piece of furniture, and I wanted it to look correct when it was finished. It came to me after ~60 years of regular use, so it needed some attention. The top had a lot of flaws in the finish and several dark rings and stains from water/condensation. I stripped the top with a green stripping product, then removed the remaining finish residue with a furniture refinisher product and cleaned the surface with mineral spirits. I then used this acid (very mild solution with water) and applied it to the bare veneer with a spray bottle, applying a light misting on the surface and then gently working it in with a sponge. After letting it dry, all dark rings and stains were gone and the wood looked like new! I treated the surface with a solution of baking soda and water, wiping away any remaining acid. I then lightly sanded the surface and proceeded with the new finish. It came out looking like new. This stuff works! Review: Rust removal & cleaning stones - This work great for some geode stones for cleaning the outside, soaking them overnight -any kind of natural rock or stone that you collect and want to get as clean as possible. Also awesome with removing rust from old tools. ## Features - OXALIC ACID 99.6% PURE (Dihydrate) - Deck, Crystals and Metal Cleaning - Rust Removal, Wood Stain Remover and More! - Usage instructions found underneath Technical Specification.

Also awesome with removing rust from old tools. ### ⭐⭐⭐⭐⭐ Exllenct for Varroa Mites *by S***N on June 19, 2024* We use this powder to kill Varroa mites on our honey bees. We have not had any infestations yet and being consistent with this helps keep our bees healthy and safe. this package is not too much powder nor too little, it will last us a long time. Be careful when using this for that application, the smell penetrates masks and cheap ventilators, a high-quality ventilator is needed to prevent the acid from going into your lungs. highly recommend ## Frequently Bought Together - OXALIC Acid 99.6% 4 oz (Ounces) Deck, Crystals, Metal Cleaning- Rust Removal, Wood Stain Remover and More! - Varomorus Durable OXALIC Acid 12V Vaporizer VARROA MITE Treatment --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/72715488-oxalic-acid-99-6-4-oz-ounces-deck-crystals-metal](https://www.desertcart.tn/products/72715488-oxalic-acid-99-6-4-oz-ounces-deck-crystals-metal) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-28*
