When mine stops working I play with it in the bath. It always comes out OK. Doesn't matter if you prefer streaight or bent. Make sure that you give it a good shake afterwards to remove any excess moisture. Repeat the bathing process if anyone else plays with your instrument.
Some people dunk their's in a mug of boiling water, but I find this a bit extreme. You will find though that it will be very easy to bend after the hot water treatment. If you're a straight player you may need to wait a while until things cool down, otherwise blowing may produce unexpected results.
