Know When to Wash Them
"You know to keep personal hygiene in check with regular bathing, but did you know your bath towels should hit the showers themselves every three to four days? Ideally, you will want to alternate between two towels and wash them all together to save time and energy.
"Hand towels can fly under the radar, especially if you don't have guests often, but you should tend to these as often as you do bath towels. Wash hand towels every couple of days, since they are used multiple times a day and often by hands that are extra wet, and not always super clean, especially since Summer brings more gardening, outdoor sports, picnics, and other activities that drive us to wash our hands more often than in the Winter.
"If we're talking towels at your vacation home or Summer timeshare, the easy trick would be to wash them before heading back home, or after guests leave after a long weekend."
