シュウ酸 99.6％ 2ポンドデッキクリスタル金属の洗浄サビ除去木部のシミ抜き用

Q: How does one prepare and apply this product? Is the water/product mixture paste-like or watery?

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?

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?

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 .

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.
