    Have a brand new RCBS powder flow (Uniflow, I believe). The documentations is emphatic that it must be cleaned to get of the rust preventive material off before use for the first time.

    What areas need to be cleaned?

    What is the best way to do this? Any special chemicals? Brake cleaner? Hoppes? Old t-shirt?

    Hoppes or mineral spirits should do it. Set the hopper aside so it won't get melted with a solvent and dissasemble and wipe the metal parts down, while you are cleaning it look for metal flashing that should be removed.

    You might want to wipe down the inside of the powder hopper with a "Bounce" fabric softner to minimize static cling of the powder, too!

    Thank you, folks.

    I will give it a try tomorrow.

    Properly cleaning the new powder measure includes removing the powder rotor and cleaning it carefully, both the outside rotor surface and the powder cavity in the rotor. Also clean the inside portion of the PM frame in which the rotor turns. Reason for thorough cleaning is that powder will stick to the anti-rust agent and clog the measure.

    Good shooting and be safe.
