Playing with Lego seems very popular at the moment. In fact, research by energy comparison site Save on Energy has found the average spend on Lego during lockdown is over £70, on average!

While Lego is fun for all the family, it can result in lots of grubby hands touching and sharing it, meaning germs can spread easily.

So what’s the best way to clean plastic building blocks? Here's everything you need to know..

What to read next

Organise it

Pull all the pieces apart and separate them into different containers for washable pieces, electrical sections and bits with stickers or printed patterns.

Separate the Lego according to what can be washed and what can't. While it's okay to wash Lego blocks, avoid letting anything electrical or blocks with paper stickers get near water!

Wash carefully

Add lukewarm water to the container and a few drops of washing up liquid and disinfectant or Milton Sterilising Fluid.

Using your hands, gently agitate the bricks and leave to soak for at least 10 minutes. If the water looks very murky, repeat the process with fresh water and detergent, and leave for a couple of hours or overnight.

GHI TIP: For washable parts, Lego don’t recommend machine washing as it could damage the plastic. Your machine manufacturer may not be too impressed either!


Remove dirt and dry

Scrub any ground-in dirt using a toothbrush or tooth pick for hard-to-reach areas. Pour through a colander and hold under running water until all the soap has been removed and they look clean.

Lastly, you can tip the Lego onto a towel and dry.

GHI TIP: For electrical parts – rub all over with an alcohol wipe or antiseptic wipe. For non-washable parts – use a dry toothbrush or wipe gently with a damp ecloth.
