Towel manufacturers recommend washing colored towels every three to four days, but if the towels are kept in a ventilated place away from moisture, you can wash them once a week. An electric towel rack is ideal for drying towels on a daily basis.
Wash towels separately from other clothes as towels tend to absorb colors. They also shed lint, which can spread to other clothes, including wool ones.
Separate towel loads produce the best results. Separating white towels from colors is very important.
Using fabric softener on your towels can shorten their life and lighten them, they can make the fabric soft but decrease its absorbency.
