Tips for dusting/cleaning your LEGO MOC layout



LEGO models are something that people love to show off and take pride in, especially when they are on display for all to see, but dust and dirt will inevitably collect on them, and the accumulation of dust and dirt on the bricks can make them look dull and unimpressive. But fear not, there are ways to clean LEGO models without damaging them. It is important to use the right cleaning techniques and materials to ensure that the models are not damaged during the cleaning process. In this article, we will explore how to dust and clean your LEGO MOC using a paintbrush or vacuum cleaner According to the operation demonstration in this video.

Why Use a Paintbrush or Dust Cleaner?

Cleaning LEGO models can be a daunting task, especially if they have intricate designs and delicate parts, as it is important to maintain their appearance and increase their longevity. But the good news is that you can clean your LEGO MOC with just a paintbrush or a vacuum cleaner. Using these tools is a safe and easy way to clean your LEGO models without damaging them. A paintbrush with soft synthetic bristles can easily brush away dust and dirt from between the studs, while a vacuum cleaner can help you clean those hard-to-reach areas.

The easiest and most effective way to clean LEGO models is with a paintbrush. But not just any brush will do. An artist-sized paintbrush with soft synthetic bristles is ideal for dusting between the nubs of LEGO bricks. These brushes can easily remove dust and dirt without scratching or damaging the bricks. It is also important to note that the ferrule of the brush should not come into contact with the bricks, as this may cause scratches. To avoid accidental damage, it is recommended to dust LEGO models regularly before dust accumulates.

How to Clean Your LEGO MOC with a Paintbrush?

Cleaning your LEGO MOC with a brush is an easy and effective way to remove dust and dirt. Here are the steps to follow:

Step 1: Get a paintbrush with soft synthetic bristles. An artist-sized one is better than the ones found at hardware stores, and may be the cheapest available. A variety of handle lengths can be useful for reaching into different-sized models.


Step 2: Hold the paintbrush like a pen and use the bristles to brush any dust from between the studs of your LEGO model. Be careful not to scratch the bricks.

Step 3: Work your way around the model, brushing off all dust and dirt. Be careful not to apply too much pressure to the brush, as this can damage the bricks.

Step 4: Once you have brushed off all the dust and dirt, use a vacuum cleaner or duster to remove any remaining loose dust.
Step 5: Repeat this process for all of your LEGO models, and your LEGO display will look shiny and new in no time.

Tips to Keep in Mind While Cleaning with a Paintbrush

Although cleaning your LEGO models with a paintbrush is a safe and easy process, there are a few things you should keep in mind:

Always use a brush with soft synthetic bristles. Hard bristles can scratch the bricks.

Avoid using a paintbrush with a metal ferrule (the metal piece that connects the bristles to the handle), as it can scratch the bricks.
Use light pressure when brushing to avoid damaging the bricks.
Do not brush over stickers or prints on the bricks as they may be damaged.
Be sure to brush all dust and dirt from between the bricks to prevent it from settling and becoming difficult to remove later.

How to Clean Your LEGO MOC with a Dust Cleaner?


A vacuum cleaner is a great tool for cleaning your LEGO models, especially those with hard-to-reach areas. Here are the steps to follow:

Step 1: Get a vacuum cleaner. You can use a can of compressed air, a handheld air blower, or an electric vacuum.


Step 2: Hold the vacuum cleaner at a distance from the LEGO model and use it to blow away dust and dirt from between the studs and from hard-to-reach areas. Be sure to blow gently to avoid damaging the bricks.

Step 3: Do this for all your LEGO models and your LEGO display will soon look like new.

Things You Should Avoid When Cleaning

Washing with Mixed Solution

Isopropyl alcohol is often used to clean LEGO bricks, but it is important not to confuse it with nail polish thinner or remover. Nail polish remover takes longer to evaporate and can damage the paint on the bricks. When cleaning LEGO models with isopropyl alcohol, it is recommended to use a soft cloth or cotton swab to gently clean the surface of the bricks.

Washing with Hard Water

Air-drying LEGO bricks can cause mineral deposits on the bricks if the quality of the tap water is not checked. Hard and salty water tends to leave residue when air dried. To avoid this, it is recommended to dry the LEGO bricks with a microfiber cloth after cleaning them with water.

Cleaning with Whitening Detergent

It is important to make sure that no dust is trapped between the studs of the LEGO bricks. Once it settles, it becomes difficult to remove without wiping the bricks with a wet rug, Swiffer duster, or soft-bristled kitchen scrubber. Avoid using powdered detergents when washing LEGO bricks in the dishwasher, as the detergent particles can act like little sandblasters and damage the bricks. The same applies to washing machines, where whitening detergents should be avoided when cleaning LEGO bricks.

Cleaning with Magic Erasers

Magic erasers, which are made of expanded melamine foam like sandpaper, are not recommended for removing dirt from LEGO bricks. Rubbing the bricks with a 2500 grit rubber will cause the bricks to wear out. Avoid washing chrome LEGO bricks in soapy water. Only do so if the chrome is not peeling.

To Sum Up


Regular dusting and cleaning of LEGO models will help maintain their shine and newness for a longer time. By following these simple tips, you can keep your LEGO models looking their best and ensure that they continue to be a source of joy and pride for you.
