Strange question. I get sticky feeling on the steering wheel. Whilst driving. Had it on my old car vinyl covering and now on the new car leather.
I regularly lightly clean the wheel with plain warm water to minimise effect and I keep my hands clean, but it returns after a few days. So I assume it's natural oil from my hands. Tried talc before but that only delayed the onset, and seemed to make it worse.
My wife uses a bit of Flash Clean & Shine in warm water to remove the sticky from our steering wheel (leather). On holiday, with no Flash available, she uses kitchen wipes (the moist sort).
