Wash your towels in hot water with a cup of vinegar, and then run again in hot water with a half-cup of baking soda. That will strip your towels from all of that residue and mildew smell and will actually leave them feeling fluffy and smelling fresh. ***Do not add laundry detergent to either wash. Just once with vinegar and once with baking soda. *** This trick also works well with wet bathing suits that were left to dry.
Step 12: Add some goodies for your guests, such as tiny toiletries, flowers, wrapped candies, or a little note. By a note, I mean something sweet and welcoming like, "Make yourself at home!" as opposed to something like, "Mess up my towel folds and you're DEAD!"
