Last time when I used to go to a gym, the norm was to sit/lie on a towel and keep the equipment clean that way. I think that is the best way. After that, I think cleaning up after yourself is better. It prevents the sweat from soaking in and discoloring the upholstery and being more difficult to clean. Also I like the opportunity to signal concern for others, at no great cost. ;-p
