Greetings,

If you have more than one shower in your house try taking showers in
both on alternate days. If your shower cutain has a lot of extra folds
that stay folded you might try one which is smaller (or make yours
smaller). You might also consider installing sliding glass doors. Or
you could have a topless maid over to clean them each and every time
your wife lets them get a spec of mold.

Hope this helps,
William
