[Hallicrafters] Alcohols

[TC Dailey]

Not the drinkin' type:

"Rubbing" alcohol is only 70% (look at the label) - the other 30 percent is 
water and often, glycerine.  The glycerine can leave a sticky film on 
things, which is why it's simply AWFUL for cleaning tape and video heads.

"Medical" alcohol is 91% - great for cuts and bruises, but it doesn't CUT 
oily films or ink-type marks.

"99.9% Isopropyl" alcohol is used for cleaning, and prep of surfaces.  When 
I worked for an avionics company, we used it for removal of rosin from PC 
boards as well.  It WILL cut through Magic Marker and ball-pen ink, removes 
cigarette smoke films, and cleans oily films from things (very useful and 
RECOMMENDED for cleaning rubber parts).  If you're going to PAINT 
something - after the wet-sanding and washing... then AIR drying... moisten 
a CLEAN cloth with this stuff, and wipe down the surface - then a final wipe 
with another DRY (clean) cloth - ALL of the paint will stick.

NOTE:  If you clean rubber parts with it, "relube" it with silicon spray (on 
your fingers) - THEN rub it onto the parts for a like-new appearance that 
will LAST.


...and that's the truth Pffffft!
