How often do you need to replace the cleaning solution? What is the average cost to replace?I clean anywhere between 50 to 100 at a time when I clean them. You can do more but that's the number I found works best for what I want. It lists for most sonic cleaners that you can do 300 to 500 223/5.56 case at a time, but the more you do at one time the longer the clean time.
