I've found to dissemble, clean (brake cleaner spray works nicely).
Relube with zoom spout turbine oil.

Oils such as sewing machine, three in one, or WD-40 tend to dry up and
stop working in a few weeks or months.

how are the bearings? Does it turn freely? use sewing machine oil
for lubrication. use wd40 if you want to ruin it.

are the brushes and commutator visible? signs of wear?

If it's a cheap POS, you should just replace it.
