Learn how to wash LEGO bricks with these four tips

[From the question: How do I wash LEGO Bricks?]

There sometimes comes a time when you need to wash a pile of LEGO bricks. It might be because they are dirty from regular use or, maybe, you have purchased a pile of pre-loved bricks. Either way, there are many different ways to wash LEGO bricks. Here are some of the suggestions:

We don’t recommend washing items with stickers, electronic parts or paper in this fashion. Make sure they are removed first and are cleaned with a damp cloth. Do not immerse them in water.

1. Washing machine

This is perhaps one of the easier ways to wash LEGO Bricks. Place the bricks in a delicates/lingerie bag or a pillow case and place in the washing machine as you would with regular washing.

Tips for using this method:

  • Use a cold or warm wash.
  • Add towels or something similar to prevent the bricks slamming against the walls of the washing machine.
  • Don’t over fill the delicates/lingerie bag or pillow case.
  • Make sure the pillow case is sealed shut either by knotting the end or using a twist tie.
  • Ensure the pillow case is not worn. Older pillow cases are likely to rip from the LEGO bricks and you’ll end up with LEGO bricks loose in your machine (personal experience).
  • Once the cycle has finished, spread out the LEGO bricks on a towel to dry. You may need to flip some of the bricks over the make sure they don’t hold any water.

2. Dishwasher

Similar to the method for the washing machine but make sure you only use the top rack.

3. Bathtub (or sink/basin)

This method is great for those without a washing machine or dishwasher. Fill the tub with cold or warm water. Swish the water around a bit and leave to soak for a bit. Swish the water around some more and then drain water and rinse the bricks. Again, spread the bricks out on a towel to dry. You may find that some bricks are not totally clean and may need redoing.

4. Individually, by hand

Sometimes you have to use this method if the bricks do not clean as well as you had hoped. I recommend the use of a “magic” white sponge – especially for removing marker pen or other types of ink. The sponges are usually available in the “sponge” section of your local supermarket. Sometimes they can be purchased from discount stores which can be more economical as they do not last very long.

Some people like to use a toothbrush but this can damage the bricks if you press too hard.
