2. Step-by-Step Guide: How to Clean LEGO Display Areas Properly
This is the core of any LEGO display cleaning routine. Always start with dry methods before adding any moisture.
2.1 Dust Exterior Surfaces First
Starting dry prevents smearing and protects bricks from micro-scratches.
Steps:
Begin at the top of the display and work downwards.
Use a soft brush to lift dust from shelves and case tops.
Follow with a microfibre cloth in straight lines.
For open displays, you can:
Vacuum using a brush attachment
Cover nozzle with thin mesh (like old tights) to prevent part loss
Learning to clean LEGO display setups this way extends the life of both cases and models.
2.2 Clean Acrylic or Glass Display Cases
Exterior
Remove the case if possible
Wipe with microfibre + acrylic-safe cleaner
Never use paper towels
Premium acrylic cases like those from brickzonehub.co.uk demand gentle cleaning to preserve their clarity.
Interior
Start with compressed air
Follow with a dry microfibre
If lightly dampened, dry immediately
This avoids streaks and scratches.

Most how to clean LEGO sets guides stress:
Never dismantle sets for routine cleaning.

Avoid:
Water near stickers
Liquids near printed elements
High-pressure air
This protects delicate details on UCS, Technic, Icons, and modular builds.
2.4 How to Clean LEGO Minifigures
Minifigures collect dust quickly, especially capes and helmets.
Steps:
Remove from the display
Brush individually
Dry-wipe with microfibre
For deeper cleaning:
Only soak non-printed parts
Never soak capes or old prints
This keeps your minifigure displays worthy of a collector’s room.

Rinse using a colander
