However, make sure you air your jeans between wears to freshen them up.
You can also try the freezer trick: fold your jeans and put them in a sealed plastic bag, then put them in the freezer for 24 hours. Freeze cleaning doesn’t remove dirt, stains or germs, but it does give them a quick refresh.
If the jeans have a stain, try spot cleaning them (with water only) rather than washing the whole garment.
