The way I clean my tungsten draw plate when it gets dirty is with
However I don’t use burr life for a lub. I use liquid dish washing
detergent. I saturate a piece of felt with the detergent & clip it
above the hole(s) being used with a paper clip so the wire contacts
it prior to entering the the hole.
Then when the draw plate needs cleaning I place it in a pan of warm
water & brush it with an old tooth brush or similar. Be sure to dry
it off very well when done so the steel doesn’t rust. If you have a
ultrasonic cleaner, that could also be used.
