Oxalic acid main applications include cleaning or bleaching, especially for the removal of rust (iron complexing agent). And also use as general metal and equipment cleaning, purifying agent and intermediate for many compounds.
Handling Procedure ::: —
Donot contact with skin and eyes. May cause burns or irritation. Harmful if swallowed. Can be Neutralised by use Ammonia or Borax, or wash with water.
DO NOT allow solution to get into gloves or soak through clothing to skin.
When completely successful, oxalic acid cleaning will remove all traces of yellow-orange iron staining, for example, a specimen of clean dark smoky quartz and pure white feldspar. Many specimens, however, are too thoroughly iron-coated to achieve this goal, and the feldspar will always retain some pale red color. Yellowstained, greenish-looking amazonite becomes a clean, bluer shade after cleaning.

REMOVAL OF IRON STAINS
Iron stains can be removed by scrubbing the stained area with an aqueous solution of oxalic acid in water. Dissolve 1kg oxalic acid to 6Lt of warm water. Scrub stained area using a stiff-bristle brush. Thoroughly rinse with water after treatment. When completely dry, lightly sand the surface. Surface must be clean and
completely dry (not just surface dry) before refinishing. Incomplete drying and retained subsurface moisture can cause finish adhesion failure.
