You won't have to worry about it in short terms. In longer terms, if you know if got a thourough soaking, it wouldn't hurt to have the axels cleaned and greased. It can be suprising how quickly some rust can build up in there sometimes. Its just fine short term. No worries, especially if its a newer bow. If it has a bit of age to it, it wouldn't hurt to have them cleaned and greased anyway.
