Just to recap, last weekend I received the ultrasonic cleaner. Have ordered Birchwood case cleaner from local gun shop but have not received it to date. On receiving the ultrasonic last Saturday 15th Sep tried it on a few cases,they cleaned up but still had dirt in primer pockets and crud inside cases (once fired Lapula ) it will be interesting to see results with case cleaner added.Sorry to bring up an old subject ,but the 15th was first time I had used Panasonic's .I have been shooting full bore fifles for 30 years . Cleaning cases with vibration cleaner and corn Cobb.
