OXALIC Acid 99.6% 8 oz (Ounces) Deck, Crystals, Metal Cleaning- Rust Removal, Wood Stain Remover and More!

Great product. Love the packaging. Works how it’s suppose to

We somehow got a nasty stain splattered down a handmade cabinet door, soaked into the veneer. I tried everything in our house, but nothing would clean it off. I dissolved maybe a 3 parts water to 1 part of this miraculous stuff, and the stain came right off, without bleaching or discoloring the wood. It is like the stain was never there. Amazing. Surprisingly, it worked on its own as it soaked in -- I had stopped scrubbing but the liquid was still on it (the door removed and lying flat), and the stain just kept disappearing without my even scrubbing any further.

I bought this because I have read in many sources that oxallic acid will bleach out the color changes made by water stains on wood. I have used "Bar tenders Friend" cleanser up until now. If mixed at the proper proportions this does a great job. Brush it on and around the effected areas as a paste, let dry and brush off. You will have to use some water to dilute the residue. Do not let the water stand. Wipe it up quickly. I hope you get as good of result as I.

The product arrived promptly and as described. I used this to clean some rocks we found and a mine. They are clean, and bright now. Did such a great job at cleaning all dirt, rust, and whatever else was on them. My only issue is there were no directions in ratios to use. I "YouTubed" it. (8oz to 1 gallon of water is what I used) But now I know, and if I have more to clean, I will purchase again.

This product is just the thing for removing rust stains from wood. Since it is an acid it will remove other stains as well. Sometimes this is a difficult item to find at most places. Amazon seems to have the best price I could find after doing some research.

Worked well on my window sills before I varnished them. Had not found anything else that worked to lighten wood. This did.

I used this to clean my old, 1971 white fiberglass boat. Little bit goes a loooooooooooong way. And the results were incredible! Removes stains and rust and old built up dirt. Just beautiful and so white. Really brought it back from the tanic water of central Fl inland lakes. Then waxed it and wow. Great product, will buy it again and again. No need to buy the expensive products that contain less than 9% of this ingredient, just throwing your money away. Use gloves , mask and safety glasses. Hooked for life! Thank you!

Excellent cleaner for stained Teak wood. Had a difficult stain, applied several times until stain disappeared.Will definitely buy again.
