You MUST rinse it immediately in COLD water after each swim.
Also wring it out after that and hang to dry. Do *not *use the centrifugal swimsuit dryer.
I always spin dry mine. What is the reasoning behind wring dry and not the dryer?
I’ve been wondering recently, what’s the hygiene take on the centrifugal swimsuit dryer? Gym locker rooms are famously havens for stuff like whatever bacteria causes athlete’s foot, made me wonder whether everyone sticking their suits into the same dryer is wise…
Athlete’s foot/tinea pedis is fungus–not bacteria. The suit dryer isn’t terribly clean or ever cleaned, but at least it is usually chlorinated water being slung around in it.
I have a Durafast suit probably approaching 300 hours now and always use the spin dryer. Still doing well. It is looser, sure, but my last Speedo was a potato sack of a completely different color after 40 hours.
Sorry it hasn’t been good to you.
