Clean your LEGO® bricks the right way

From time to time, your LEGO® collection will need some freshening up. We take a look at various methods that people of the web have shared, as well as a few ideas of our own.

What The LEGO® Group says

First off, The LEGO® Group recommends that you wash your LEGO® blocks by hand using a mild detergent (something akin to Sunlight liquid) in water temperature of no more than 40℃. They add that you should take care to rinse the detergent off properly to avoid any discolouration. Let them dry naturally, or carefully dry each brick using a soft dry towel

Using mild bleach

This one is for those badly soiled LEGO® bricks. The LEGO® Group recommends that you use a very mild bleach and perhaps it’s worth also saying that you shouldn’t leave the bricks in to soak for longer than a few minutes.

Brighten up yellowing bricks

Older bricks tend to yellow if exposed to too much sunlight – especially the white, blue and light grey LEGO bricks. You can rectify this using hydrogen peroxide. According to Brothers Brick, the bricks undergo a chemical reaction to the H2O2, that effectively helps to bring the colours back up. You can get 100ml bottles of hydrogen peroxide from Clicks for about R16. Here’s a step-by-step whitening method that AFOL John Tooker swears by.

Stick ‘em in a laundry bag and into the washing machine

If you’re pressed for time and needing a quick cleaning solution, then this might appeal to you, however, be warned that there’s a high chance that your bricks will sustain scratches. The LEGO® Group itself warns against putting your LEGO® bricks into the washing machine or dishwasher. But, some LEGO® users attest to this method, adding that they run the machine on a lower temperature wash. This LEGO® cleaning method is probably used most by parents that need a way of getting sticky food stuff off their kid’s LEGO® bricks quickly and with the least elbow-grease.

Keep clear LEGO® pieces shiny

Since tiny scratches show up more on the transparent LEGO® pieces such as windshield, so do keep them separate when you give your LEGO® bricks a good clean. To restore these pieces back to a shinier version of themselves, someone has discovered the wonders of wood floor cleaners. Andy Taylor has written an entire post on the subject over at The Brick Blogger, offering a step-by-step guide using Pledge WoodCare. It is the liquid acrylic that you want, which Andy later explains is “a clear very dilute acrylic medium based floor polish.”

Cleaning those minifigures

In order to keep the printed details of your minifigures intact, it’s critical that you take the utmost care when you go about cleaning them. Ebay has a great post on how to clean vintage minifigures, which is worth applying to newer minifigures.
