Sport before school. Barely any time to shower afterwards..help!?

I have badminton before school for about 2 hours, and we only get about 20 minutes to shower and get clean before school starts. (Also, there are quite a few girls on the team...and my school is probably limited on showers?) Are there any ways to be clean and not take a shower? (like clean hair, not sweaty/stinky/oily/gross feeling) ahh help! I usually take a shower before school if that does anything..!
