Look after your swimsuit

It will last much longer if you rinse immediately after you take it off (salt water from the sea and chlorine from a pool will rot elastic).

Same goes for goggles – give them a quick rinse before hanging up to dry. Wash swim caps in cold water and dry before putting away (and if you have a lot of trouble getting a swim cap on and off, sprinkle the inside with a little talc to ease things).
