[bolivier]

I'm looking into buying a parts washer. I thought that these vibrated parts in a solution to clean the parts. The ones i'm seeing are just a glorified sink with a lid. Am I mistaken on the vibrating part. Looks like they circulate the solution to clean. Maybe i'm getting the vibrating parts from the device that my dad used to clean his surgical instruments at his Vet hospital.
Also the solution, if the parts just set in it, does it kind of melt off the grime? Is it safe for the solution to contact your skin? Just trying to get some personal experience with some of these. I was thinking a 20 gal would be big enough for most parts I would need.

Thanks,
Brent
