Sticky Knob
Hi Chaps, I wonder if you can help.
We've got a Westerboer VW900 vario with a sticky knob, sometimes it takes two hands to change the volume or turn it on. It's a single input instrument, twist and click the knob to turn on, keep twisting to turn it up. The shaft of the knob (sic) goes through the glass and into the instrument.
Any help on how to make it turn a bit easier? I was tempted to give it a good squirt of WD and some exercise, but I don't know if that will do any good to the insides.
Much love

SGC was quick off the mark!
Anyway, where plastic, rubber and glass are involved, I'd suggest silicone grease/spray/ release agent.
AFAIK, the basis of WD40 is fish-oil, very effective 40 th. attempt to formulate a Water Dispersant.....However, it dries outand becomes viscous. Silicone doesn't and does not attack most plastics. Also commonly sold in car-accessory shops as Vinyl shine or Dashboard cleaner . Sewing suppliers(haberdashers) sell it for machining plastics/rubbers/tarpaulins.....makes the material slide under the needle without puckering and bunching!
