.... are absolutely disgusting. Biohazards.
I'm doing a mewant wrap on it. I hope I can get it right, this is not going to be an easy project, but before I do it I'm cleaning the alcantara.
I first used the Sonax alcantara cleaner. The goo that came out is literally the most disgusting thing I've ever had to do work with while cleaning a car. Nearly two decades of oily hand juice from everyone who's ever touched the steering wheel came out. Previous owners and all.
It still wasn't clean, and right now the steering wheel is removed and getting a much needed bath in my warm soapy sink with dish soap. Obviously the electronics are removed. Still the water is turning a color that makes me want to call the pope.
Leather can naturally absorb and process this material. Alcantara is synthetic. As much as we want to believe in the miracle of modern science, it still can't hold a candle to the actual miracle of nature.
YUCK.
