For proper sanitation, towels require changing after three to four applications. Alternating between two towels permits complete drying between uses, requiring washing approximately every two weeks. Ignoring this schedule creates musty aromas and causes white towels to appear grayish eventually.
Bath mats need more regular attention. Their moisture, combined with bathroom warmth and darkness, produces perfect environments for mold and bacterial growth. Bath mats should receive weekly washing to eliminate debris and maintain bathroom cleanliness.
