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

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 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.

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.

Reasonable price
