Washing the Bricks

Tips and Tricks

Cleaning frequently used LEGO® or DUPLO® is easy and sometimes necessary!

Separate all the pieces, each one needs to be taken apart to be properly cleaned. To save time, get the kids to help!

If you have a lot of bricks to wash, put them in a mesh bag. Place the separated bricks in a container, sink or bathtub with hot water and add your usual mild detergent or dish soap to the water. We recommend that you wash your LEGO pieces by hand using water that is no hotter than 40°C (104°F). Never use cleaning agents that contain bleach.

Shake the bricks gently with your hand. You don’t need to clean each piece by hand unless you really feel it’s necessary. Allow the bricks to soak. After at least ten minutes, if the water is extremely cloudy, replace it with fresh soapy water. Leave to soak for a full hour, or overnight if necessary.

Disinfect. Add ¼ cup of white vinegar to each cup of hot container water.
Rinse well with clear water. Place the LEGO bricks in a sieve or colander and rinse under cold water to remove the soap and loosened dirt.

Dry the bricks. You can also spin the bricks in a salad spinner to remove some of the water. Then place the wet bricks in a single layer on a towel, right side up, so that the water runs off the underside. To speed up the drying process, blow the bricks with a fan.

Never put your LEGO bricks in the washing machine or dishwasher, and don’t try to dry them in the oven, microwave or with a hairdryer. If the bricks get really hot, they can change shape and won’t work!
