Of course here in the tropics we don't need airing cupboards,

What? What? Walk around in soggy clothes do ya? Or are you on a nudist island?
Living in Philippines for a year I learned that the oven (set on warm) was a good place to get the damp out of towels before showers or baths and we left the light on in closets to keep mildew and damp at bay.
Had a heated towel rack in Hawaii which was put to multiple use warming up clothing and linens.
Liked it so much I bought one (Hammacher Schlemmer has them) for here in NE where it is on all winter and used off-and-on when summer weather turns "muggy."
