Wash and dry bath towels before using them for the first time. Most towels have silicone or other finishes. Washing the towels removes these finishes and permits maximum absorbency.

To set colors, wash colored towels with similar colors in warm water for the first several washings. Using about half the recommended amount of detergent, add 1/2 to 1 cup of white vinegar to the wash water. The vinegar helps set the colors and removes excess detergent residue.

Wash towels every three to four days. Use warm water and color-safe bleach (if needed) for colored towels. Use hot water and nonchlorine bleach (if needed) for white towels.

Give your towels a shake when taking them out of the washer. This will help fluff the terry loops that aid absorbency. Don't iron terry towels; this will reduce absorbency.

Ensure that towels are dry when you remove them from the dryer. Even slightly damp towels can quickly mildew, but avoid overdrying; it can destroy the integrity of the individual cotton fibers.
