According to Jordan :

Better to use something designed as a penetrating solvent rather than
a Water Displacing liquid.

I take the point, 3in1 OK?

No -- 3in1 is also something which gums up over time. It is
actually better as a furniture polish than as a lubricant. And it is
certainly not a penetrating solvent.

Better to get something which actually claims to be a
penetrating oil, such as "Marvel Mystery Oil", which has always been
better than 3in1 -- though there are more expensive oils which may be
better overall.

Good Luck,
DoN.
