You don't really need gloves, just keep your hands clean when you are driving. I started to keep a packet of non-fragranced wet wipes to make sure that I don't spoil it if I was at a petrol station or messing in the engine bay.
I try to do a weekly light clean with a lightly damp microfibre cloth, then a more in-depth clean using a good fabric cleaner and a fabric protector every 12 months or so:
This is originally from Jack to help with keeping it looking great:
Alcantara cleaning:
In order to preserve the beauty of Alcantara it is recommended that regular cleaning is carried out.
Daily cleaning:
It is sufficient to dust Alcantara using a soft brush, a dry cloth, or a vacuum cleaner.
Weekly cleaning:
After having dusted Alcantara, run a slightly moistened white cotton cloth over it. Avoid the use of printed absorbent cloths/papers as they can release ink onto the material
Yearly cleaning:
Dust the material with care; moisten a soft cloth or a sponge in clean water, wring it thoroughly and run it over the whole Alcantara material, making sure
not to wet it excessively; rinse the cloth or sponge and repeat as necessary.
Leave to dry (overnight). Once dried, in order to restore the material, brush it delicately with a soft bristle brush.
It may seem like too much hard work, but the result is an amazing steering wheel feel, grip and it also looks pretty cool
