RE: Whistling Tube Question

I've never had a case extreme enough to use fine grit sandpaper or steel wool. But some here on AA have.

Others have successfully used De-Oxit.

My "goto" combination is "NeverDull" metal polish followed by a thorough rinse with Isopropyl alcohol. You can use cotton balls or swabs.

Or, if you break a cotton swab in half, you can insert it in a Dremel and get amazing results polishing and rinsing at the low RPM setting.

Just be wary to shield the spray when doing the polish and rinse. I even follow up with a dry swab in the Dremel to get any further residue off.

Needless to say you do go through many cotton swabs. Don't apply too much pressure and going around each pin once should be enough. Metal polishes are less abrasive than sandpaper, but should not be overused.

You should see immediate results, folling these steps.

Other metal polishes will work as well but tend to leave some dry residue behind.

And of course one must hold the tube carefully if you don't want to smudge any of the lettering.
