I'm sure others will chime in here, but this is a bad idea for long term
maintenance.  Anything you spray into a slider will improve it temporarily.
(As a joke test once I even showed that maple syrup poured into a
slider will 'fix' it.  Which it did, for a while).

However, DeOxit 5 is specifically designed for metal on metal contacts.
No claims of suitability for metal on plastic or on resistive elements.

The long and painful and correct answer is to take the 2600 apart, remove
the sliders, disassemble each one, clean the parts, add something like
Lubriplate to the plastic slide mechanism on top, and reassemble.

That is the only way to keep them up and running for the long term.

I'm starting to wonder about some ARP sliders that I've been seeing
recently where the resistive element no longer has a response across
the entire travel and I wonder if it's because over the years various
sprays have started to dissolve the resistive coat.  (no facts yet,
just conjecture on my part).
