-Do not mix your cotton bed sheets with polyester products when loading them into the washing machine in that polyester fabric has the tendency to pill and shed the same pills on to the cotton fabric.
-Use half the commercial detergent recommended; this will reduce damage to fibers and clean your linens just as well.
-Wash in cool water that's less than 104 degrees F.
-Dry on low heat
-Set wash cycle on gentle
-Use the extra rinse cycle if available
-Avoid using bleach as it breaks down fabric fibers
-Dry sheets in the dryer only until they're dry
-Avoid over drying
-Remove sheets from the dryer promptly and fold immediately
-If sheets have cooled in the dryer and wrinkles have set, then tumble another 5-10 minutes with a washcloth that has been slightly dampened.
