hello, I have a brass mp mold for a couple of years
every time it costs more for the boolits to fall when you open it
I clean it with a toothbrush and soap before using it, and I lubricate it with the lubricant that the MP molds bring
Today I rubbed the cavities and the vent lines with a piece of wood, then cleaned it with brake cleaner.
no apparent improvement
Is there any way to clean it better than the ones I used?
