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.

2.3 Cleaning Assembled LEGO Sets

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

Slightly damp microfibre cloth

Wipe gently

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.
