I favour broad spectrum "sports" type creams. These are usually of lighter consistency than the general alternatives, so perhaps don't make you sweat quite as much. Even so they are difficult to remove at the end of the day -- particularly if out in the sun longer than 4 hours and have had to reapply the cream, it is difficult to remove from arms, leg and face.
I'm talking about at home where after a bike ride I generally scrub as much dirt/sunscreen off as I can using paper towels and then use soap. The same thing that makes the sunscreen stick to you even when sweating etc, means it's very difficult to get off. Ordinary soap does not do the job. I guess some kind of abrasive soap in combination with the paper towel precursor would be best.
If I move this scenario to camping where there is not necessarily limitless supplies of water etc, how best to remove the cream so I can spend a reasonably comfortable night and not oil up the sleeping bag liner?
For hiking I have never worried much -- I wear long shirt / pants, so it's only my face. For mountain biking in summer however, I would be wearing short sleeves/shorts. The cream accumulates a lot of dirt.
How do you deal with this?
