Here is what I do; but you need to make up your own

needs:
Where would you place perc on the list of solvents? Often sold as
auto brake cleaner or as dry cleaning liquid. It does seem to bother
some, but not all plastics (probably doesn't sit well with styrene).
The bicycle folks have some great oils, drip-less and
synthetic (wont
oxidize and gel into goo with age). Or use good old 3-in-one oil.
3inone is pretty light, some things like larger electrical motors need
a bit heaver oil like 30W motor oil . There might be specs on the
motor for this, or the documents. In my case I usually have to guess;
small light weight gets 3in1, if it weighs over a pound... 30w.
In brass band instruments, there are any number of very light oils
used; some synthetics as well (e.g. Hetman, Binak). I like to use
plain old Ultrapure lamp oil because it's cheap, very low viscosity,
doesn't smell and will evaporate with time without leaving residue.
Heavier alternatives are 5 weight "white oil", used on sewing machine
and embroidery equipment. I've heard of people using Marvel Mystery
Oil on their equipmet as well, as it's only about SAE 3 weight.
Any professional tribologists on the list?
