Golf GTD steering wheel after nearly 47k miles - looks as good as new. I hate it when it gets grimy particularly after filling up at the diesel pumps, so give the wheel a wipedown with a magic sponge once a month.
Does it not take the leather dye out as well? Is the sponge not impregnated with harmful chemicals? Sounds like no? I keep a pack of ‘Water Wipes’ for use throughout the car on the go and they are good, but the steering wheel doesn’t stay matte for long.
