Citric Acid Pickle
If you are looking for a safer and more environmentally friendly way to pickle, then this product is for you.
Use Citric Acid just as you would any other pickle. Use Citric Acid Pickle in a 7 to 1 ratio (7 parts water to 1 part pickle) when heating your solution in a pickle pot. You can use Citric Acid Pickle cold, but you will need to increase the ration to about 3 to 1. It is BEST to use distilled water when creating a citric acid pickle solution.
Fill your pickle pot with water, then add the citric acid. It is VERY IMPORTANT to add the citric acid to the water. You can use any tweezer with this solution. You can add more water to the solution if you need to, but it isn't necessary to add more citric acid until the solution stops working. Your solution will work for months
You can use Citric Acid Pickle on gold, silver, brass and copper. Remember, warm or hot solution will give you best results in removing fire scale. When done, it is a good idea to rinse your pieces in a solution of water and baking soda to neutralize any acid residue.
Be aware that when picking brass or nickel, some of the copper in the alloy may surface. It can be removed with soap and a wet brass brush or steel wool.
KEEP OUT OF THE REACH OF CHILDREN. DO NOT INGEST
Citric acid is used as an environmentally friendly cleaning agent that occurs naturally in fruits such as lemons, limes and oranges. Due to its organic nature, it is subject to mold if left alone for long lengths of time. Using distilled water and keeping your containers sealed when not in use will greatly delay any mold.
Citric acid itself is non-toxic and biodegradable and can be poured down the drain. However, any pickling solution becomes saturated with copper which can cause major problems for a septic system and even a water treatment facility. If in doubt contact, you local waste management for advice.
