[CW] Clean Contacts - DeOxit can be tricky

[Guy Letourneau Owner]

DeOxIt is a two-part cleaner; you use their #8035 "Cleaner" first, wipe off everything that got all over where you didn't want it, (does that ever happen?!?) 
but you then follow up with DeOxIt "Shield" product #8036. 


I also like CRC's QD as a stand-alone product. 



If you don't get the handy, hollow swizzle-stick applicator, you can line up a few wooden-shaft cotton swabs if your application allows those things to access contacts, 
or spray onto a gun cleaning patch if you're working on a car-spring-sized variable inductor. (I had a Palstar AT2KD that started getting scratchy-sounding within my first 6mo of use.) 



QD leaves almost no residue, so if the spray has stripped off the lubricants off of spindles, you'll need to go back and add fresh oil. 
3-In-1 seems to work fine for non-energized mechanical movements, and most hardware stores carry electric motor oil in a small can for energized joints. 


You can also use the straw to clean-up inside potentiometer cans, if these have any apertures to let you get in there. 


You can find decent pricing and credit card ordering at grainger.com or mcmaster.com, the latter was of course the old McMaster-Carr corporation. 


Just my experience, YMMV of course - humidity / temp / corrosion, how close you are to open salt water,

This one is 100% and comes with a brush:

There is also a needle dispenser, 100%, I use this for rotary potentiometers (I.e. volume controls), and for contacts I use a strip of 100% cotton bond (thesis paper), press the needle downward on this to dispense a drop of DeOxIt, then close the contacts and run the contact surface by pulling the paper through the contacts. 
Guy, would this be a correct procedure? Also if you could suggest some names for suitable substitutions for 'Relay-Kleen', I'm sure everyone would be very grateful.
