First we set the standard by counting the number of 2×4 Lego bricks in a pound: 180 bricks. Jun 2, 2009
Can I put Lego in the washing machine?
You can add a mild detergent to the water – please rinse them well with clear water afterwards. Please don’t put your bricks in the washing machine or dishwasher. Air-dry them at room temperature – never dry them in the oven, microwave or with a hair dryer.
