[Hallicrafters] Re: Cleaning Tubes

[Rich Oliver]

I clean my tubes dry with #0000 steel wool - the really fine stuff.  It 
does a fine job on everything I've tried, especially the old UV-199 and 
similar vintage tubes with water soluble markings.  It works quickly and 
leaves no residue - just blow away the dust and you're done.
