Gun Nut,
Do you use anything to neutralize the Citric acid or do you justy add a teaspoon to the US cleaner ?

A solution made from 5% citric acid and 95% warm water is chemically the same as neat vinegar, Don’t put it on chips though as vinegar is made by fermenting ethanol to produce acetic acid that’s why it tastes different but chemically it’s the same,If your water is very hard you may need to increase the amount of citric acid.

You make a neutralizing solution by mixing 1 teaspoon of baking soda (not baking powder) in 1 litre of warm water. Do a 8 minute cycle with both solutions.

The water should be hot to the touch but not boiling excessive heat makes brass brittle drying in a towel on a radiator is fine but don’t put them in the oven unless you have one with a very low setting.

Remember when you clean this way you are not only removing the dirt from the case you are actually dissolving the brass, only by microns but thats why it works.

Hope this helps

Citric acid is not Acetic acid. They are two different chemicals. C6H8O7 and CH3COOH.

Acetic acid does not taste like Citric acid.

Vinegar can be produced many ways, a lot of which will flavour it (wine vinegar, balsamic vinegar etc), but pure Acetic acid is just strong vinegar (vinegar is usually a 5% to 20% solution).

Lemon juice is a complex mixture. It is around 8% citric acid.

I see what happened, please read what you wrote again, you got mixed up. Citric acid ain't vinegar. You meant to write Acetic acid.

Vinegar = dilute Acetic acid (5% - 20% w/w).

If you dilute Acetic acid, you can indeed put it on your chips and it tastes the same as white vinegar.

I picked up some powdered citric acid today - citric acid monohydrate (e330) to be exact.

Could one of you knowledgeable chaps give me a starting point strength wise?

Cheers

I am using citric acid. On cleaning 20 cases, I fill the U/C 's tank with warm water to cover the cases then add one rounded teaspoon of citric acid and give it 2 cycles of 480. Other people may have a different recipe for this amount of cases.

After these two cycles, I heap a teaspoon of bi carb into some clean water to negate the affect of the citric acid before drying off.

I use citric acid as compared to distilled vinegar, this is a cheap way of doing your cases.
