Review: Affordable varroa mite treatment - 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.
Review: Removes Red Clay Stains - 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.

## Questions & Answers

**Q: How does one prepare and apply this product?  Is the water/product mixture paste-like or watery?**
A: Dissolve it in hot water.  Will be watery. Scrub hot solution in with a brush.  Then make sure you clean it up with water after don’t leave any residue.

**Q: Can you use this on a metal rusted roof?**
A: I have used it on metal corrosion on our fleet of sailboats for years and have been very pleased with the results.  I have tried other products and found that almost nothing else works.  If you plan to repaint after removing the rust/corrosion you will need to make sure your wash the surface several times with fresh water.  For stubborn areas, you may need to do a little wet sanding with very fine sandpaper (300 GRIT or higher).  If you have any wood in the area that you don't want bleached (e.g. a wood deck or stairs) you should cover it and then hose it down as soon as possible if any of the oxalic drips on it.

**Q: Is this a good product to use for removing rust stains on pavers and travertine?  What is the mix ratio?**
A: I have successfully used about a tablespoon per quart of water for removing paver/concrete rust stains.

**Q: Can a mix be used to remove rust from inside a fuel tank? I would  think it would be more gentle and less likely to produce pin holes .**
A: Yes. It works well. I have used it in a Ural gas tank, which was stored for 13 long years with bad gas. This stuff in hot water removes all rust pitting from inside the tank. I had to use baking soda mixture to neutralize the process.
I then used a pint can of the Red Kote to line the tank. Great results.

### ⭐⭐⭐⭐⭐ Works amazingly well on iron stains
*by K***B on October 14, 2024*

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.
