The VW Golf GTI Clubsport and Clubsport S models have an alcantara rimmed steering wheel, and some owners on the VW forums have commented on the alcantara showing early signs of wear; after just a few thousand miles.
Quite a few years ago we conducted an experiment in the Club Clio where a few of us with alcantara and leather wheels thoroughly washed our hands and avoided any kind of hand cream, lotion or such while the rest went on like any other sane person would do to operate their vehicles.
At the turn of one year, the amount of tear and wear on the "normal cars" was considerable, while those of us who took the extra steps to have decontaminated hands when driving had our steering wheels close to new in appearance and feel.
I know there are a bunch of variables to take in account, but was an interesting experiment nonetheless, and it's something I have been doing ever since in every car I drive. As you can guess, I have never ever had any issue with my steering wheels, be it alcantara or leather, OEM or aftermarket.
