I bought myself a pair of ron hill running pants and long sleeve tee, but aren't sure how best to look after them. Is it necessary to wash the tee after every run? I know the ron hill tees are meant to deal with sweat better than regular tops, but after my run this morning it was soaked through. I've just left it to dry on a heated rail. Is it ok to do this and maybe wash it once a week? I don't want to be susceptible to bacterial infection or anything.
