It’s recommended to wash and change your towels every three to four uses to maintain hygiene and prevent bacteria and mold growth. Towels, especially when damp, provide an ideal environment for microbes to thrive, which can cause skin irritations and unpleasant odors. If you use a towel daily, it’s a good practice to switch it out for a clean one at least twice a week. Additionally, ensure towels are fully dried after each use and washed in hot water to kill any bacteria. Keeping a fresh supply of towels and maintaining proper laundry habits can help ensure a healthier and more pleasant bathing experience.
