How to Remove Oxalic Acid Oxidation

When compared to other acids like nitric or sulfuric acids oxalic acid is considered weak. It forms salts (or compounds of a metal and nonmetal) with most of the alkali earth metals (magnesium, calcium, and strontium) that are commonly referred to as lime buildup, calcification, and oxalates. There are several methods for removing oxalates and most involve the use of a strong acid. The steps outlined below use a common and moderately safe acid called muriatic or hydrochloric acid.

Things You'll Need

  • Object with oxalate build-up
  • Muriatic acid (from hardware store)
  • Water
  • Small plastic basin
  • Latex gloves

Instructions

    • 1

      Fill the basin a quarter way full with water and pour the muriatic acid up to the half-way mark of the basin to make a 50-50 solution of water and acid. Be sure to use gloves when handling any acid.

    • 2

      Soak the object with the oxalates or calcification in the basin for several minutes until most of the buildup is gone.

    • 3

      Rinse the object off with tap water to remove any excess acid.
