Tumbler or Sonic Cleaner

[Ex Crab]

25 years ago I bought a Dillon vibratory cleaner which I always regarded as being very good at cleaning cases. Then about 10 years ago acting on a tip from a friend I bought an ultrasonic cleaner and use 25% solution of common toilet cleaner (no chlorine!). The stuff is dirt cheap and very effective, about 10 minutes in the machine and the cases look like new. They then get drowned twice in a bucket of water and stood to dry on old newspaper. I use that method on my 38 Spl cases and on rifle cases, especially those used for reduced loads. It is reassuring to be able to see the powder in the bottom of a 30-06, as opposed to looking into a black hole.
9mm and 45 ACP just get the vibe treatment.

I wonder what the active ingredient in that is? I wonder what the long term effect will be?

According to the list on the bottle it contains less than 5% non-ionic tensides, organic acids and colouring agents (available in blue, purple, yellowish and pink!) The tensides are a wetting agent or surfactant. Long term effects? Clean cases! Seriously short term contact with a diluted solution (20-25%) and thorough rinsing afterwards has no apparent ill effects on the cases. My 30-06 cases for the Springfield look like new after 6 reloads and 38 Spl cases easily survive 12 loads before they get junked. They could do more, but 38 Spl cases are more than readily available at my club so I can be choosy.
There are of course proprietry cleaning agents available at € 5.00 or more per litre as opposed to € 0.70 per litre for bog cleaner. No competion there.

Which sounds like no damage over term. Unlike some other things...that can be used.

Going on the basis that a picture speaks a thousand words, here's a few thousand words, I think that the difference is noticeable:

They look about new.
