i use green plastic industrial gloves that are large enough to wear over cotton gloves, and go about 5" beyond my wrist. i roll up a cuff to accept the inevitable oil running down my hand, as it is hot. my filter placement does not allow for a clean and dry change. i use ramps, even though they're not needed, as it makes an underside visual inspection easy. i lay down an old plastic shower curtain liner that i save just for this job, in case of spills. when done, all waste rags/paper towels are folded up in the plastic, and there is no mess. the rest is basic. it's a 2 beer job (3 if it's mid summer). as for as oil being a carcinogen -- as long as you're not ingesting it, or getting it on your skin every day -- don't worry about it. you'll find a method that suits you. good luck.
