[AMRadio] Best product for noisy potentiometers / How to salvage the contents of inoperative aerosol spray can?

[Rob Atkinson]

PB Blaster is great.  They're getting into the variety game though and
make a few different types.  One is labeled as being for garage doors.

Last year I used Blaster to free up a sewer lateral access cap in my
basement.  It did the job in FB style, but the basement stank for a
couple of days.

Use Blaster outside as much as possible.

I've seen WD40 for sale in metal gallon cans not under pressure.
Can't remember where I saw it that way.  A gallon would be a lifetime
supply for me so I didn't pay close attention to it.
