sticky pots

I bought some old pots on ebay. They are rather sticky and take quite an effort to move. Is there any kind of lubricant or technique that I can use to free  them up a bit?

best wishes

Dit you test them with a knob attached or only by turning directly on the shaft? Believe me, that makes a big difference, since as bigger the knob the more force you get and more travel in your fingers (physics  ::slight_smile: )

… and if they’re really new, they’re gonna loose a bit of the “tightness”.

indeed, only on the shaft.. they look very old.. thanks for the tip
