Oxalic acid is a traditional pickling agent, and the crystals make a stable, long lasting pickle solution. Oxalic Acid is a highly concentrated pickling acid. You can subsitute it for pickling crystals if you wish. Oxalic Acid is also used to bleach or lighten chrome leather. It is great for pickling when you use it prior to using almost any tanning solution. Works great with Lutan-F.

To start out, mix 2 teaspoons of oxalic acid for every gallon of water. Use hot water when mixing. DO NOT breathe in the fumes and or vapors while mixing oxalic acid. This could result in your lungs being burned. You should maintain a pH of 1 to 2. PH test strips work well for measuring levels of pH.

Make sure you allow the acid solution to cool to room temperature before adding any pelt or hide.
