Ultrasonic Cleaning Solutions

I've looked through the ultrasonic cleaning threads and most seem to suggest using vinegar. I haven't seen anyone comment on citric acid.

An experienced palma shooter in my club uses a couple of teaspoons of citric acid powder,from baking aisle at supermarket) in a bucket of warm water. He puts a lid on the bucket and spins it on some rollers for a while and gets clean cases out. He doesn't use a neutralisation step and has no discolouration of the brass.

Since I have a ultrasonic cleaner on the way and citric acid will be cheaper per litre than vinegar I would like to know if anyone has tried citric acid in an ultrasonic cleaner?

If I use vinegar can it be re-used multiple times or does it need to be replaced with each run?

I love this stuff. It really does a great job.

Citranox

Thanks Barry. Unfortunately Citranox doesn't seem to be available in New Zealand. Looking at the data sheets it is 10-30% Citric Acid, probably with a small amount of detergant to get the surfactants.

I'll give a 15% Citric acid with a few drops of dish washing detergant a go and see what happens.
