Questions for reloaders who use ultra sonics cleaners:
What type/brand of solution do you use?
Any good homemade recipies?
How many cycles/how much brass can you use before replacing the solution?
A squirt of Dawn and a teaspoon or two of lemi-Shine or citric acid and HOT water.
The Lyman, RCBS, and Hornady concentrated cleaners all seem to work well, but so does the above.
Tip: Deprime all cases before cleaning (using a Lee Universal Depriming Die or equivalent). Otherwise, you are trapping water in the primer pocket and NOT cleaning the primer pocket.
