Cleaning Brass Post Office Box Doors

[Ed Pawlowski]

All you need is a motor and arbor. Mine is home made from decades ago. I had a guy at work make the arbor for me in the machine shop.

Some people call those arbors that go on the ends of motor shafts "widow makers" CP

If the objects are removable, the old barrel-of-sawdust with a few blocks o'wood and a pint of metal polish, slowly turned by a motor, will tumble it clean and smooth in a lazy day.

Nevr-Dull Magic Wadding.

After 11 years, I hope the brass is clean. In fact, it is probably time to re-do it. Lew Hodgett told him how.

Great on chrome! Never tried it on brass.

I was outta the AF by time I discovered Nevr-Dull, so tried to avoid brass like the plague. I usta weld/sil-solder brass/copper, but we always had nitric acid(?) dip tanks to chemically clean both. This at a govt lab.

Hmmmm.... I gotta all brass pepper grinder I can try my old can of Nevr-Dull, on. The can may be TOO old. The wadding tends to dry out, after a few yrs.

Pull it out of the can and tear off a bit from the bottom of the "roll." That stuff lasts forever. I think the can I have sitting in the shop is now 25+ years. Never tried to reconstitute it, but I suppose it's possible. Naptha is a major component.

Smells like it.

Takes rust spots offa chrome like nobodies' business. I kept my Trumpet Bonnie shining like the proverbial sun, with that stuff. ;)
