Hi to all,
Just thought I'd share my DeOxit'ing procedure..
Here in Australia I've only found the small bottles of deoxit that come in a handy kit. D100L which is the cleaning solution with a touch of lubricant and G100L which is lubricant with a touch of cleaner.
If its easy get to the wiper of a pot, I will just add a very light smear, with the applicator brush, onto a piece of white paper that I've cut up into a thin strip. That piece is then gently slid under the wiper, as the wiper is rotated, the crud will be left behind to see on the paper. I'll re-do this a few of times or until the paper is no longer dirty. Then I just rotate it back and forth while having a little cleaner on the wiper as to clean the portion of the track the wiper runs on. Also there are the other sprung contracts that are made to the wiper that can be difficult to reach. I found that a very fine artist brush (not too cheap that it loses its bristles) that's lightly coated with cleaner is good to apply here, just avoid contacting with the shaft. All cases where I've slipped a thin piece of paper under the wiper I've not felt that I could be widening its gap to much for firm contact to the carbon disk, it feels unstressed and there is, I've seen, enough tension for it return and operate again normally, but do take care.
Once dried I will then add a tiny amount of the lube to the wiper(s) and rotate. You will notice things are smooth and you haven't disrupted the shaft grease at all. Let dry and then test if able, chances are in most normal cases that'll be sufficient.
Attached is a random Google picture of the parts I've described cleaning.
This way has kept me from loosing the "feel" of a pot, as can happen if the cleaning chemical and methods (aerosols come first to mind) have washed out the "once only" shaft grease. Yes, it's a slow way but also a sure way. Hope I've helped.
