Legos

Children’s toys are a breeding ground for germs. A dishwasher does quick work of disinfecting toys that are washable, like Legos. To quickly clean Legos:

  1. Drop the Legos in a laundry bag to keep them contained.
  2. Run your dishwasher as usual.
  3. But, remove the Legos before the drying cycle, letting them air dry completely on a towel.

This is how often you should toss your kitchen sponge.
