Curado E series

[Wackyrig]

Anyone got a fix for the older E series Curado knob on the handles replacement? Sticky looking to replace. Had them all serviced only issue is the knob stickiness.

I wrapped my sticky knobs with finger tape.

It's oozing plasticizer out of the plastic, much like a plastic worm will do in enough time. Clean it up with something abrasive like baking soda, lava soap or scouring powder. Citrus based solvent or acetone may also help, isopropyl alcohol may not be strong enough.

Other approach is just to buy new handles.
