I wonder if anyone can suggest a suitable contact cleaning
method - one suggestion Ive had is connect 12v thru 500ohm resistors to NO and NC and leave them switching for about 5 minutes
Some of the relays of coarse can be dismantled and cleaned but most cannot - any comments please -- Mike GD6ICR IO74PF73TW
