[CW] Clean Contacts

[sbjohnston at aol.com]

I've used it, but the 100% D100 fluid is less handy in my experience.  I found it has to be put on, then wiped off, just leaving a thin film behind.  

The DeOxit D5 can be sprayed on and left - including relays.  I still prefer to just use a little bit, carefully delivered to just the metal contacts, but I've never had it mess anything up.

The D100 has been too "thick" several times and caused some issues.

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.
