As long as you are putting the crib sheets in the washing machine after your stain treatment, it is not necessary to dry the treatment area. If you are spot treating only and do not plan to wash it in the washing machine, be sure to dry the area thoroughly (a hair dryer on low heat works great).
Mold
When subjected to prolonged moisture, any natural fiber is a candidate for mold. High humidity, high temperatures, darkness, and stagnant air can all contribute. Here's how to treat it. In general, it is best to wash your crib sheets in hot water (only for mold). Hot water kills mold more effectively than cold water and better removes mold spores and allergens too.
Vinegar is another option. It kills 82% of mold species and can usually kill the mold growing on fabrics. Vinegar will also remove the moldy smell from fabrics. You can soak your crib sheets in a vinegar solution and/or add vinegar to your washing machine.
Then put your crib sheets in the washing machine along with detergent and let the machine fill with water.
