Lubricating my joystick

[zahnartz62]

I have an X52 Pro js..there is a slight frictional resistance, a "grab" when I make small adjustments to my flight path and in formation flying. I was thinking of WD40 but do not like the perfume odor (except in the garage) and also silicone grease on the spring and dished baseplate. But the actual rubbing may be down the hole at the base of the stick. Amy advice welcome..many thanks in advance. John
