Here is a trick that I learned “on the road” about how to freshen up your clothes without laundering them. This works really well on cotton fabrics (jeans, etc.) and I haven’t tried it on delicate fabrics, so if something is expensive, don’t try this technique.
Use one Wet Ones hand sanitizing cloth (citrus scent is good) and put it on a hanger (draped over the flat rod part) hang your clothes on the hanger and wait a day. The fabric will be fresher and ready for a few more uses. If you have no place to hang your stuff, put one Wet Ones cloth in a plastic bag with your clothing item and seal it closed it for about an hour. Remove clothes and air out for a while before using.
This technique works well for outer garments only.
