5.7 brass cleaning

Recommended Posts

5.7 has a special lacquer coating that is used to help feeding and such.  Heard tumbling is out.  Some use 10% solution of simple green in a ultrasonic cleaner.  Others just wipe it clean and lube and reload.  Number of reloads are few by my understanding.

I have reloaded it for about a year and its a very finicky round and the data isn't abundant. However, accurate and vita vhouri both work well. I'Ve been just wiping the brass but it looks grungy, not that it matters, but I like the brass to be a bit cleaner.

 

Heavyopp there is a coating as pointed out that needs to be preserved. It's also important to have.a good she'll holder. I had one made by a machinist on the FN forum.

I can always check to see if the alcohol removes the lacquer.  If not I can use something milder like simple green.  If not I'm going to soak it in car wash soap and see what happens.
