Tube Cleaning?

[ma7t93]

any good methods to remove lift residue from the inside of mortars?

I use an air compressor. If that does not get the debris out then use a clean out stick.

Turn upside down and shake. Works most of the time.

As for any other residue, don't worry about scrubbing or anything.
