Rookie Mistake

[Mark Beasland]

This is very interesting. Over the years I have ultrasonic cleaned LOTS of parts and never had a damaged barrel set, part or spring. I use diluted dollar store cleaner degreaser in a heated tank. Hard for me to believe ultrasonic cleaning that won't damage case color, solder joint or blueing and won't touch rust will damage sound spring steel. I have never used simple green.

When my main spring broke on the 1861 repro lock plate it had been in the Brownells Steel White overnight. It had not been touched. The solution and lock plate were both at the same temp. as they were both stored in my garage. No agitation. Just sitting in the solution. Pulled it out and the spring was broken in two pieces. Now this spring was probably only twenty years old.
