OXALIC Acid 99.6% 4 oz (Ounces) Deck, Crystals, Metal Cleaning- Rust Removal, Wood Stain Remover and More!

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.

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

I had to do research and lookup YouTube videos on how to use this on wood, but other than that was satisfied with this product.Note: if you’re using to bleach/lift stains on wood, mix about 1/3 oxalic acid, 2/3 warm to hot water and stir until it dissolves and apply to the wood. Could also do 50/50 and it may work better. You don’t have to apply it any special way. I used a paintbrush. But use it evenly across the wood. Let it dry until, I waited 24 hours and then rinsed the dried crystals 1-2 times with just water on a wet washcloth to ensure that all the acid is removed and is also neutralized.

Works great for treating our bees.

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!

It was easy to use, did what I needed to do. Clean my crystals from my dog in Arkansas.

Use a vaporizer works fine. Cost less than at bee stores.

This time it didn't remove blood from fabric
