My mother was ‘thrifty’ and would rarely let my dry clean my clothes, so she made me do this, something I’ve been doing for many years since to freshen woolens and jackets that are not really dirty.
Put them in a dryer with a wet, wrung-out washcloth. But don’t use a hot setting, only warm, and only for 20 minutes. Hang them up immediately so you don’t have any wrinkles!
If they’ve picked up an odour like smoke, dissolve a little baking soda in the water you use to douse the washcloth first. You can put a couple of drops of essential oil directly on the washcloth, too.
