Your LEGO display cases protect your valuable collection, but they need regular maintenance to stay crystal-clear. Fingerprints, dust, and smudges can quickly diminish the visual impact of even the most impressive builds. This comprehensive guide shows you exactly how to clean LEGO display cases properly without causing damage.
Why Proper Cleaning Matters for LEGO Display Cases
Acrylic LEGO display cases require specific cleaning methods to maintain their clarity. Using the wrong products or techniques can cause scratching, clouding, or permanent damage. Regular, proper cleaning keeps your cases looking new whilst ensuring your collection remains visible in all its glory.
What You'll Need to Clean Display Cases
Before you start cleaning your LEGO display cases, gather these essential supplies:
- Microfibre cloths (at least two—one for washing, one for drying)
- Lukewarm water
- Mild washing-up liquid (avoid anything with harsh chemicals)
- Spray bottle (optional)
- Soft-bristled brush for stubborn dust
- Acrylic-safe cleaner (optional, for stubborn marks)
Step-by-Step Guide to Cleaning LEGO Display Cases
Step 1: Remove Loose Dust
Start by gently removing loose dust from your LEGO display cases using a dry microfibre cloth. Use light, sweeping motions rather than pressing hard—this prevents scratching the acrylic surface. For dust in corners or edges, a soft-bristled brush works brilliantly.
Step 2: Prepare Your Cleaning Solution
Mix a few drops of mild washing-up liquid with lukewarm water in a spray bottle or bowl. The solution should be gentle—too much soap can leave streaks on your display cases. For UK collectors, standard Fairy Liquid diluted heavily works perfectly.
Step 3: Wash the Display Case
Dampen your microfibre cloth with the cleaning solution—it should be moist, not dripping wet. Gently wipe the LEGO display case using circular motions, working from top to bottom. Pay special attention to areas with fingerprints or smudges, but avoid applying excessive pressure.
Step 4: Rinse Thoroughly
Use a clean, damp microfibre cloth with plain water to remove any soap residue from your display cases. Soap residue can attract dust and leave streaks, so this step is crucial for maintaining crystal-clear acrylic.
Step 5: Dry Completely
Immediately dry your LEGO display cases with a clean, dry microfibre cloth. Water spots can be stubborn on acrylic, so don't let the case air-dry. Use gentle, circular motions to buff the surface to a streak-free shine.
What NOT to Use on LEGO Display Cases
Protecting your investment means knowing which products to avoid when cleaning display cases:
Never use ammonia-based cleaners like standard window cleaners—they can cloud and crack acrylic over time. This includes popular UK brands like Windowlene or standard glass cleaners.
Avoid paper towels, which can scratch acrylic surfaces. Always use soft microfibre cloths for cleaning LEGO display cases.
Don't use abrasive cleaners or scouring pads, which will permanently scratch the acrylic and ruin the clarity of your display cases.
Skip alcohol-based cleaners, as they can damage the acrylic's surface finish and cause clouding.
Dealing with Stubborn Marks on Display Cases
Removing Sticky Residue
For sticky marks or adhesive residue on your LEGO display cases, use a small amount of white spirit on a microfibre cloth. Test on an inconspicuous area first, then gently rub the residue until it lifts. Follow immediately with your standard cleaning routine.
Eliminating Stubborn Fingerprints
Persistent fingerprints on display cases often respond well to a dedicated acrylic cleaner available from most UK hardware stores. Alternatively, a solution of one part white vinegar to three parts water works brilliantly for stubborn smudges.
Removing Static and Dust Attraction
Acrylic LEGO display cases can develop static that attracts dust. After cleaning, lightly mist the surface with an anti-static spray designed for plastics, or wipe with a dryer sheet to reduce static buildup.
How Often Should You Clean LEGO Display Cases?
The cleaning frequency for your display cases depends on your environment:
Weekly dusting: Use a dry microfibre cloth to remove surface dust from all LEGO display cases.
Monthly deep cleaning: Perform the full washing routine for cases in high-traffic areas or those showing visible fingerprints.
Quarterly thorough cleaning: Deep clean all display cases in your collection, including those in low-traffic areas.
UK homes with pets or near busy roads may require more frequent cleaning due to increased dust and airborne particles.
Preventing Damage to Your Display Cases
Proper Handling
When moving LEGO display cases, always lift from the base rather than gripping the sides. This prevents flexing that can cause stress cracks in acrylic over time.
Placement Considerations
Position your display cases away from direct sunlight to prevent UV damage and reduce dust accumulation. In UK homes, avoid placing cases near radiators, which can warp acrylic through heat exposure.
Regular Maintenance
Consistent, gentle cleaning is better than infrequent aggressive scrubbing. Regular maintenance of your LEGO display cases prevents buildup that requires harsh cleaning methods.
Cleaning the Inside of Display Cases
If dust has accumulated inside your LEGO display cases, you'll need to remove your builds temporarily. Use the same gentle cleaning method on interior surfaces, ensuring everything is completely dry before replacing your LEGO sets to prevent moisture damage.
Professional Cleaning Products for Display Cases
For collectors with extensive LEGO display case collections, investing in professional acrylic cleaners can be worthwhile. Look for products specifically formulated for acrylic that are available from UK suppliers. Brands like Novus or Plexus offer excellent acrylic care systems.
Restoring Scratched Display Cases
Minor scratches on LEGO display cases can often be buffed out using acrylic polish and a microfibre cloth. For deeper scratches, acrylic scratch removal kits are available from UK hardware stores. However, prevention through proper cleaning techniques is always better than restoration.
Maintaining Multiple Display Cases
If you have numerous LEGO display cases, create a cleaning schedule to make maintenance manageable. Rotate through your collection, cleaning a few cases each week rather than attempting to clean everything at once. This approach keeps your entire collection looking pristine without overwhelming your schedule.
Storage Tips for Spare Display Cases
If you have empty LEGO display cases awaiting new builds, store them properly to prevent damage. Keep them in a cool, dry place away from direct sunlight, ideally wrapped in soft cloth to prevent scratching. Never stack heavy items on top of acrylic cases during storage.
