Florida Laboratories OXALIC Acid 99.6% 2 Lb. Deck, Crystals, Metal Cleaning- Rust Removal, Wood Stain Remover and More!

I bought this product to act as a wood bleach. It reacts very quickly and well with tannins in discoloured wood to restore the wood's natural colour. Although I have not rtied it for other purposes this product is also recommended for rust removal etc.

Saw on an Amish You Tube video on using this to remove hard mineral deposit in toilet. Works fantastic in 15-20 minutes, no scrubbing!

I use it on my bees. It kills the mites

I have a high iron content in my well water. After getting a filtration system that solved the problem, I had to deal with the iron stains on shower tile, toilet bowls, and sinks. I mixed up some oxalic acid at a 1:16 ratio (actually used 1 Tbsp per cup of water), put it in a pump sprayer, and sprayed the shower tile. I walked away for a while and when I came back the tile looked like new! Not a hint of discoloration. So I sprinkled a small amount (probably about a Tbsp) in the toilet bowl and let it sit. Abracadabra, the stain disappeared. I wish I’d known about this is my previous house when I had badly rust stained toilet bowls. This stuff really works! Just be careful when mixing it that you don’t inhale the powder, it will make you cough and sneeze. This stuff is worth every penny.
