Re: clean brass
Cartridge Case Cleaning Solution
I have been using this formula for many years and it works just fine. It cleans and brightens the brass. Don't leave the brass in this mild acid solution for more than thirty minutes or you may find, it turns pink. The pink is the copper, after the zinc has been etched away. You will find the recipe with instructions, below.
Cartridge Cleaning Solution by T. Vincent
1 Cup of White Vinegar
1 Teaspoon salt
1 Tablespoon liquid dish washing detergent
Place all ingredients in a 1 gallon clear glass bottle and fill with Warm Water. If you plan to store the case cleaning solution, for any length of time. Place cellophane food wrap over the top before you put the cap on. This will prevent the vinegar from attacking the aluminum cap.
I use a 12 x 9 x 3 square plastic container that fits perfectly in the sink. Put about 100 cases in, add the case cleaning solution and agitate with your hands every five minutes, for about 15-30 minutes, depending how dirty they are. Rinse and dry on an old bath towel on the floor.
