The Platinum Series Rotary Tumbler delivers a new level of brass cleaning performance. This 220 volt model is designed for use with European electrical outlets. Rotary tumbling with stainless steel media in a liquid bath gets brass much cleaner and works much faster than ultrasonic or vibratory tumbling methods. The pins easily penetrate inside cases and into primer pockets to deliver unbeatable cleaning power. The tumbler can effectively clean without stainless media pins by using a mixture of Frankford Arsenal Brass Cleaning Solution and water (the media pins ensure primer pockets and inside of cases are perfectly clean). The Frankford Arsenal Platinum Series Rotary Tumbler is the most effective brass cleaning process available.
