I made up beds for guests over half-term, and noticed that the pillow-cases smelled less than delightful. Not nasty, just a bit musty and stale.
I hadn't used them for some months, but they'd been kept in the airing cupboard, together with all the rest of the bedlinen and towels. So everything was clean from the laudnry and quite dry.
I don't use fabric conditioner, so wonder whether that was why the pillowcases smelled a bit off.
What can I do about this? How can I ensure that stuff that goes a long time between uses still smells pleasant?
