Oxalic acid (H2C2O4) is a relatively strong organic acid and is a common reducing agent in organic chemistry. There are a number of methods for preparing oxalic acid from nitric acid, and one important difference among them is the amount of oxalic acid that is produced from a given amount of nitric acid. Oxalic acid can be prepared in a laboratory with nothing more than sugar and nitric acid, although a small amount of vanadium pentoxide will act as a catalyst and allow the reaction to proceed much more swiftly. more »

Depending on the surface that is stained, rust stains can be particularly hard to remove. Concrete and other porous surfaces are more difficult to clean than sealed surfaces such as vinyl or ceramic tile, and often, the rust has gone unnoticed for a great length of time on cement surfaces such as garage flooring.

Oxalic acid is the common name of ethanedioic acid. Oxalic acid is not a tanning chemical but is used for curing or pickling after tanning. It helps tanned hides achieve a plump texture and makes it easier to shave the hide with a round knife.

Oxalic creates a low pH in the final product and increases tanning by 50 percent. more »
