Yeah don't use grease ... grease was just a poor word choice, 3-in-1 oil is
what I used, but not always easy to get, depending where you live.

'3 in 1' is one brand, 'sewing machine oil' is another good term to

The sort of stuff model train people use.

3 in 1 oil is rather brown so when it eventually dries out what's left
will be quite thick and sticky like tar. A light pale coloured sewing
machine oil would be my choice.

All oils that are blends of various fractions of oils will thicken as
they dry out.
Top quality oil is a blend of far fewer....and yes, Id go for sewing
machine oil
