I was a freak about keeping my bike clean & always used wax instead of oil on the chain. Sometimes grime was unavoidable like when it was raining so I carried a moist towel in a ziplock bag in my backpack. I also had a chain clip on the rear stay so it wouldn't flop around and brush into things. When removing a wheel the key is to hold the spokes, not the tire and rim. Spokes should mostly always be clean with a bit of maintenance - they don't need oiled after all. On my set of Mavic wheels that was somewhat dangerous since they had oval spokes which were a bit sharp. I did cut myself on them a few times.
