SoapNuts smell a little like vinegar, will my clothes smell like this?

Your clothes will have no scent at all. If you like scented laundry add a couple of drops of your favourite essential oil to the washbag. Try using lavender oil for sheets and pillowcases for a relaxing sleep, lemon oil for work clothes to make you feel fresh and sharp, and tea tree for cloth nappies for a little bit of extra antiseptic and antibacterial protection.
