Started reloading in 1972. At the time it was all about economy, being able to afford to shoot while paying the bills and feeding the kids. I cleaned my cases in plastic buckets, starting with dishwashing soap and followed by two rinses, each done overnight.
By the early 1980's I acquired a nice used tumbler with a drum capable of accepting about 100 rifle cases or 200 pistol cases. Used that with general satisfaction for about 10 years.
Next up was a vibratory tumbler. Greater capacity, but usually required several hours to get a batch done and annoyingly loud while operating. Also, the media (walnut shells) can tend to leave dusty residue overall, and occasional chunks lodged in primer pockets or case interiors. Not a bad machine, but ended up giving it away a few years ago.
49 years into the reloading game, now I am back to plastic buckets with soapy water and double rinse, air dried. None of my reloaded ammo is sparkling bright or shiny, but it always works.
Confession time. I frequently process and reload my brass several times between cleanings. Seems to work just as well without adding another tedious chore. Clean enough seems to be clean enough.
