Stiff tuners

[Rabbie]

I need some advice on something I have never done. My folding bass's tuners have got really stiff due to constant windings and unwinding. Is it ok to use a wee bit WD40 or is it a no-no and there is something else better?
Thanks in advance y'all.

Rabbie, I'm no expert but I'd avoid WD-40 or any of the other spray lubricants. These fluids are designed to "creep" and, whilst that may help initially, you don't want them subsequently creeping onto the binding post. I'd suggest a much heavier oil instead, ideally a bit of grease, but a drop of 3-in-1 will probably do the trick.

Could try a quick squirt of furniture polish..... it is a great lubricant and shouldn't hurt the finish either.

I'd suggest powdered graphite (used for lubricating cylinders locks...). Can be 'manufactured' from the innards of a lead pencil..?
