[Elecraft] CLEANING KEY CONTACTS

[KENT TRIMBLE]

Don . . .

You are correct . . . just a plain sheet of clean paper is all you need.

Do NOT use a dollar bill as some will suggest because of the human and 
leather-wallet oils with which they are contaminated.

Close the contacts on the paper until there is slight drag on the paper 
as you pull it through.  If the paper rips, the contacts are too tight.

You'll see the dirt on the paper.  Continue drawing with another corner 
of the clean paper until there is no further dirt on the paper.

It should go without saying that you must not file the contacts (though 
you occasionally come across that suggestion, too).
