USES

The most common uses of Oxalic Acid are in tanning leather and removing rust and ink stains. In stain removal, it acts as a reducing agent (a substance that donates electrons to other substances) and is relied on by most dry cleaners for this purpose.Iron rust stains contain iron in its oxidized form (Fe III); the Oxalic Acid reduces it to its colorless reduced form (Fe II). Oxalic Acid is also used to clean metals in many industries and is also used in the purification of glycerol (glycerin).
In many industrial processes Oxalic Acid is used to remove calcium ions from solutions. The reaction of calcium ions with Oxalic Acid produces an insoluble solid, calcium oxalate..

Also great deck cleaner…..
