Review: SUPER PRODUCT - STRONG!!!! - Living rural, on a well, sometimes leaves one wondering what to do about the never ending rust stains in the toilet bowls. There are sprays and powders and they all contain the same MAJOR CHEMICAL as this bucket. So why not make your own, only better? Within ten minutes of getting this, a scoop was in both toilets doing its job - one in the tank, one in the bowl. A few hours later the rust was 90% gone and we were back to pretty. I have used this stuff on rusty metal files, tool surfaces.... anything with rust. Once done wipe off and spray an oily film to protect. Best to try on a small area first. Wear gloves.... and for God's sake, wear eye protection - this stuff is unforgivable.

### ⭐⭐⭐⭐⭐ Removed black ring stain from oak table.
*by J***R on December 13, 2023*

After sanding to remove water rings from an oak table, I was left with a 4" dia dark black ring stain (about 1/4" wide) that penetrated the grain. Hydrogen Peroxide did not make a dent. I applied this product, dissolved in hot water, to paper towels placed in the area of the ring and left to soak for a couple hours. That effort removed 80%. Next I wet the surface with the same mixture and sprinkled some dry oxalic crystals directly to the liquid over the ring and following grain lines crossing over the ring (to distract from potential over-bleaching in the shape of the ring). After a couple more hours, I rinsed with cold water. After the water dried, the ring completely disappeared. It reappeared faintly during staining, but 99% disappeared again (maybe even over-bleached in some areas?) after stain & subsequent poly coats dried. Now I'm just sad I did not take a before picture. I really did not think the ring was removable and am very happy with the result (photo).
