How to clean big amounts of lego while keeping them sorted set-wise?

You've purchased a collection of 15 LEGO sets from Facebook Marketplace and want to clean them thoroughly before building. The challenge is how to clean and sort the LEGO bricks set-wise after disassembling the sets.

One effective method involves using a series of containers or trays to separate the bricks by set. As you disassemble each set, place the bricks into their designated container. This approach helps maintain the set's integrity and makes rebuilding easier. You can also use the original set boxes or resealable bags to store the bricks.

For cleaning, you can use a few different methods. A gentle approach is to hand wash the bricks in warm, soapy water. Use a soft brush to remove any dirt or grime. Rinse the bricks thoroughly and let them air dry completely. Another option is to use a washing machine, but place the bricks in a mesh laundry bag to prevent them from getting lost or damaged. Avoid using harsh chemicals or abrasive cleaners, as they can damage the bricks.

After cleaning and drying, you can reassemble the sets. Having the bricks sorted by set will make the process much more manageable. If you find yourself with a large collection of LEGO, consider getting a LEGO storage organizer to keep everything tidy.
