How to dry the inside of a wing put into storage?

[bradlw]

After rinsing and hanging for 24hrs I re-empty it again then re-inflate.

These days my SI is rarely more than seven days, but I've been doing this for years with no issues when SIs were sometimes measured in weeks when I was working.

that's what I used to do... sometimes a couple of cycles lightly inflate, preferably with dry air and not breath..... let it evaporate inside a day or two with it hanging so that the OPV is the low point....then drain and shake...and repeat a time or two till I get no more water droplets out...maybe another time for good measure before putting into storage

I rinse in fresh water, then open the dump valve and hang it to dry for 2-3 days before packing it up for long term storage. No point overthinking it. It is likely damp inside when I pack it for the return trip home from the vacation destination, but thats just a days trip typically …

If I'm putting wings or BCD's into storage for a few months I do the following:
In the final rinse of the bladder I'll add some isopropyl alcohol, slosh it around and dump. Then I'll put it on a hanger with both the Inflator elbow and the dump valves removed (careful with those gaskets!!). Let it hang for a couple of days, reassemble and away it goes.

While you're at it, don't neglect that inflator. Get plenty of fresh water running through it every which way you can. I like to put a hose up to the oral inflate and push the power inflate button to get water flowing over and through the Shrader valve and coming out the QD.

I do not use isopropyl, mouthwash, bleach or anything like that in my wings. I rinse with fresh water several times with a Steramine pill dropped into the bladder. Shake it around, let it sit and then drain and dry with partial inflation.
