Plastic drain boards provide a durable place to air dry hand-washed dishes. Unfortunately, they can also become a haven for collecting germs and bacteria from standing water, especially in the utensil compartment where water drainage is not as effective. It is important to regularly clean your plastic drain board to keep from transferring those germs and bacteria to your freshly washed dishes.
