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

I have Georgia red clay on about everything in the yard and oxalic acid helped remove it from concrete, stucco and wood steps. I used a 1:16 (1c/1g) ratio and rolled the solution on the affected areas. After letting it sit for 5-10 minutes, I brushed it then rinsed it off. It worked great for painted stucco and treated wood steps. The concrete will lighten somewhat and that may be due to either the strength or that I don't need to leave it on as long. It truly is a bleach to wood and concrete. On hot days, you need to keep the affected area wet until you brush/rinse. For mud on jeans or cotton pants, I rinsed off the dirt and mud. Then I mixed 1 tsp to OA to 2 gallons of water and soaked the clothes for about 20 minutes in a bucket, then brushed the stains away. For very heavy stains I resoaked and brushed again in the same water. Afterwards I loaded them into the washing machine with other clothes. This diluted mixture did not change the colors on any the clothes.

I use this for treating beehives for varroa mites. It has worked very well so far. It is a great value for the price. The 2 pound bag will last for many treatments. Great value for beekeepers looking for an affordable treatment option.

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.

Great product, multiple purchases. This is the only oxalic acid i have used, removes rust stains just fine, and balances wood pH.

works very good to lighten wood deck

I used this product for cleaning the cedar plank siding and cedar posts on my four-year-old Tea House. My annual treatments weren't quite keeping up with the oxidation. Now, it looks almost brand new again. This product is a very strong (pure) acid. Mix properly, use your PPE, and let it do the work. Great service, speedy delivery, quality product. I used a High Volume Low pressure sprayer to apply a mixture of 1/2 cup per half gallon. Applied to clean dry wood, let it sit until it dried, then rinsed with a power washer on wide angle (or a nozzle on your garden hose). Great results. For Western Red Cedar, I like use a good coat of Teak Oil once per year. Enjoy your wood. :)

This is the same oxalic acid that is used for treating bees for varroa mites but is simply not marketed to that community. It's more economical than buying the "made for treating bees" brands and does the exact same thing. I had a bad infestation that got out of control (31 count of mites from test) and after a few weeks of treatments, I got it down below the normal threshold of three.

When I was building my deck, I cut off part of the metal roof on the existing building to connect the deck patio overhang. When I did that little metal shavings got wet from a small rain and created the black spots you see all over my unstained deck. It would not come out with a pressure washer or anything. This stuff did the trick in less than 10 minutes. Here's what I did. Wore a mask, long sleeves, pants, socks and shoes and used rubber gloves. Got a $12 sprayer at a local hardware store Filled with 1 gallon of warm water Mix in 8 oz of oxilac acid, closed the lid tight and shook it to mix Sprayed solution lightly covering each board until it was noticeably wet I covered the entire deck and by the time I was finished the other side had already cleared up completely (about 2 or 3 minutes) I bought a hard bristle broom and lightly brushed the boards but really i didn't have too. The spots just disappeared as you can see from the pictures I included. Amazing stuff.

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.

Reasonable price
