If you or your child play with Legos, BEWARE! They can be filled with germs!!! It’s best, from time to time, to sanitize Legos. Simply fill up a mesh laundry bag, place it in the dishwasher on the top rack, and let it run. Once the wash cycle is complete, remove the bag, and place the Legos on a towel to dry. They will be clean and ready to be built!
