Cleaning new Lee dies

[Nuclearcricket]

Jim, I prefer to use Denatured Alcohol. It is easy to get, in expensive and works pretty well. After the dies are cleaned I like to coat the inside of the sizing die with the same lube I will be using on the cases. This process has worked pretty well for me over the years.
Also I have found that if you change lubes at some point in time, reclean your sizing die and relube the inside of the die with the new lube.
