Deep Cleaning: When Your Models Need Extra Love

Sometimes, especially after models have been handled or displayed without protection for a while, they need more than just dusting. Here's how to give 'em a proper clean without causing damage:

1. Dust first using the methods mentioned above.
2. Prepare a cleaning solution with lukewarm water (never hot!) and a tiny drop of mild dishwashing liquid.
3. Slightly dampen a microfibre cloth or cotton bud with the solution—it should be barely wet, not dripping.
4. Work in small sections, cleaning gently and drying immediately with a clean cloth.
5. For stubborn marks, leave the damp cloth on the spot for a few seconds to loosen the dirt before wiping.

Remember: The goal isn't to soak your model but to clean it with minimal moisture. Water and metal aren't best mates, so always err on the side of caution!

Things to Absolutely Avoid When Cleaning

I've seen some horror stories over the years from well-meaning collectors who've turned to household cleaners for their precious models. Let me save ya from making the same mistakes:

Diecast Cleaning No-No's
Window Cleaners	Contains ammonia that can strip paint and damage decals. Just because it's good for glass doesn't mean it's safe for your models!
Alcohol-Based Products	Can dissolve paint and adhesives, leaving your model looking worse than before.
Abrasive Cloths	Paper towels, kitchen sponges, and regular dusters can all leave micro-scratches on delicate finishes.
Submerging in Water	Water can seep into joints and internal areas, causing rust and damaging any paper or cardboard components.

After cleaning, some collectors like to add a protective layer to their models. If you're going this route, stick with products specifically designed for diecast models or, in a pinch, automotive waxes meant for delicate finishes. Apply sparingly with a soft cloth and buff gently—a little goes a long way!

Storage Best Practices for Long-Term Preservation

When it comes to storing your diecast treasures, location is everything! I've seen too many beautifully maintained collections cop it simply because they were kept in the wrong spot. Your garage might seem like the obvious place for car models, but most garages in Australia are shocking for temperature control and humidity—exactly what you don't want.

Ideal Storage Conditions

Your diecast cars, trucks, and other models will last longest in an environment that's:

• Room Temperature: Aim for 18-22°C if possible. Extreme heat can warp plastic components and affect paint adhesion.
• Low Humidity: Between 40-50% is the sweet spot. Too dry and rubber parts can crack; too humid and metal starts to oxidise.
• Dark or UV-Protected: Light is the enemy of vibrant paint, especially models with red or blue finishes which fade fastest.
• Dust-Free: Enclosed cabinets or display cases are worth every cent for keeping dust at bay.
• Stable: Areas with minimal vibration are best. Constant shaking (like near washing machines or heavy foot traffic) can loosen parts over time.

One of the best investments for serious collectors is proper storage containers. For boxed models, consider plastic tubs with secure, airtight seals. For unboxed models, foam-lined cases with customisable compartments provide excellent protection. If you're storing multiple models together, make sure they can't bump against each other—even small contact during moving can cause paint chips.

Original boxes aren't just for show—they're designed specifically to protect your model! The custom-cut inserts prevent movement and provide the perfect support for delicate components. When possible, save those boxes for future storage needs.

Displaying Your Collection: Cases and Considerations

Let's face it—what's the point of having a ripper diecast collection if ya can't show it off? Displaying your models is half the fun, but it also presents unique challenges for keeping them in top condition. The good news? With the right display setup, you can have your cake and eat it too!

Types of Display Cases Worth Considering

Not all display cases are created equal. Depending on your collection size, available space, and how often you handle your models, different options might suit you better:

Case Type	Best For	Pros & Cons
Wall-Mounted Acrylic Cases	Smaller collections, limited floor space	Pros: Space-efficient, great visibility Cons: Limited capacity, can be tricky to install securely
Glass Cabinets	Larger collections, dedicated display rooms	Pros: Substantial capacity, elegant appearance Cons: Heavier, more expensive, glass can break
Stackable Display Cubes	Growing collections, flexible arrangements	Pros: Modular, expandable over time Cons: Less unified look, varying quality
Single-Model Acrylic Cases	Particularly valuable or delicate pieces	Pros: Maximum protection, great for special items Cons: Expensive per model, takes up more space

Strategic Display Positioning

Where you place your display is just as important as what you display it in. Consider these factors when choosing the perfect spot for your diecast cars and other models:

• Avoid Direct Sunlight: Even with UV-protective cases, prolonged exposure to sunlight is a no-go. North-facing rooms in Australia typically get less direct sun.
• Mind Your Heat Sources: Keep displays away from heaters, radiators, fireplaces, and even hot light fixtures which can affect paint and plastic over time.
• Consider Traffic Patterns: In busy areas of your home, cases can get bumped or vibrated. Quieter rooms often provide safer environments.
• Think About Accessibility: If you regularly handle your models, front-opening cases positioned at comfortable height will reduce the risk of accidents.
• Allow for Air Circulation: Some enclosed spaces can trap moisture, so ensure your display area has decent ventilation.

Creating Impressive Visual Arrangements

Once you've sorted your protective cases and found the perfect spot, it's time to think about arrangement. A thoughtful display can transform a collection from a bunch of models to a proper showpiece:

1. Theme-Based Groupings: Arrange by era, manufacturer, country of origin, or racing livery for race cars.
2. Height Variation: Use risers or stepped displays to ensure smaller models don't get lost behind larger ones.
3. Spacing Matters: Allow enough room between models to appreciate each piece individually.
4. Background Considerations: Dark backgrounds make light-coloured models pop, while neutral backgrounds work well for varied collections.
5. Rotation Schedule: If you have more models than display space, create a rotation system to keep your display fresh and give all models equal "showtime."

For those with historic models like vintage aircraft or classic cars, consider adding small information cards about the real-world vehicle. It's a great conversation starter when visitors admire your collection!

Handling Your Models: Common Mistakes to Avoid

Even the most careful cleaning and brilliant display strategies can't protect your diecast models if you're handling them improperly. The oils from your skin, accidental drops, or just plain careless handling are responsible for most of the preventable damage we see. Let's sort out the do's and don'ts of proper model handling.

The Proper Way to Pick Up and Move Models

There's definitely a right and wrong way to handle these delicate beauties:

When and How to Use Gloves

You've probably seen serious collectors or museum curators wearing gloves when handling valuable items. There's good reason for this practice:

• Skin Oils Are Sneaky: Even freshly washed hands transfer oils to models that can etch into paint and metal over time.
• Fingerprints Are Stubborn: Once fingerprints set on matte finishes or delicate surfaces, they can be incredibly difficult to remove without damaging the model.
• Acidic Sweat: Some people have naturally more acidic skin oils, which can accelerate corrosion on metal parts.

For casual handling, clean, dry hands might be fine, but for valuable diecast cars or aircraft, consider investing in a set of white cotton gloves. They're inexpensive and can prevent a world of regret down the track. Just make sure they fit well—baggy gloves can reduce dexterity and ironically lead to drops or bumps.

If you're showing your collection to others, especially kids, consider a "look but don't touch" policy, or demonstrate proper handling first. Better yet, keep special pieces in display cases that satisfy curiosity while protecting your investment.

Transporting Models Safely

Moving houses? Taking models to a show? Proper transport is crucial to avoid disaster:

1. Original Packaging Is Gold: The manufacturer's box and insert were specifically designed to protect that particular model during shipping.
2. No Original Box? Wrap models individually in acid-free tissue paper, then bubble wrap, securing with tape that doesn't touch the model.
3. Box Within a Box: Place wrapped models in a sturdy container with cushioning material between each piece.
4. Vehicle Transport: Keep model boxes on the floor of the car, not sliding around on seats or in boots that heat up.
5. Professional Shipping: If sending models through the post, double-box with plenty of cushioning and mark as "Fragile" and "Collectible".
