It’s a dream come true to own a diecast car collection that’s detailed and displays a piece of automotive history. Maintaining a diecast collection has proven difficult for many, though. Having the perfect model car collection is complex, so we opted to share this article on keeping your model car collection in good condition.

Proper Storing

Many enthusiasts store their cars in display cases or other storage solutions. A good display case and a single coat of wax will ensure they last for a long time and eliminate the need for them to be dust-free.

A prefabricated case, a favorite display casing for many collectors, can be perfect for displaying your diecast race cars. Also, they’re available in different sizes so they can suit your collection. Finally, prefabricated cases are straightforward to clean.

Alternatively, some car model collectors choose to build custom displays for their collections. Some hire professionals while others prefer to do it themselves. Building a custom display case gives you more flexibility and allows you creativity. A custom-made unit may be suitable if you need even more storage for your model cars. Remember, large cabinets with multiple shelves might need lighting to make your models sparkle. LED lights are good because they won’t cause your model cars to melt.


Unfortunately, many collectors fail to factor proper maintenance into their collection, particularly beginners. To avoid tarnishing your diecast collectibles, they should be stored at room temperature, in a relatively dry environment, and must be dusted regularly. Over time, exposed cars might tarnish, so using anti-tarnish bags is a good idea.

It’s also a good idea to invest in a car detailing kit. This kit should include things like applicators, cleaning solutions, and wax. Wax will help retain the pristine condition of your collection as it keeps it looking new.


Depending on how dirty your diecast model cars are, as well as the type of dirt on them (decal residue, dust, dried glue, etc.), you’ll need to clean them in a particular way. You can clean diecast model cars until they gleam by wiping them with microfiber cloths. Then, all you have to do is start rubbing the model down.

If streaks remain after wiping off dust with the damp cloth, use a dry part of the microfiber cloth to buff them out. A makeup brush or a soft paintbrush will do a good job cleaning out the nooks and crannies. They can also clean the surface, but they don’t seem to perform as well, and they tend to blow the dust off.

One can clean diecast model cars of decal adhesive in several ways. First, it’s possible to find products that remove residue from your model and melt your model. These harsh chemicals will strip off paint and turn plastic into lumps. Pick a product carefully for this reason. 

Your model has likely been sitting in a dirty garage or shop for a while; you perhaps found it in an obscure, dusty, and cobweb-filled place in your grandparents’ house.

Many recommend disassembling your model car if you’re comfortable doing so, but don’t force it if you’re not. How you clean filthy diecast model cars depend partly on how well you know the car and how much skill you possess. Water and an absorbent cotton cloth should be sufficient to clean your diecast car. But as a rule of thumb, proceed with caution.

It may be safe to immerse your diecast model in water, depending on your model’s material. Avoid doing this if your model has decals, has upholstered and carpeted interiors, and others. Make sure to use cold or lukewarm water (not dish soap), and submerge the car for approximately half a minute. Wipe the car down with a soft cloth, then rinse it off.

When you’ve washed the car, immediately pat everything dry. Using soap may not be necessary according to the type of grime involved. As much as possible, follow slow and attentive procedures and test new cleaning methods on inconspicuous areas.

Keep Them Away From Sunlight

The sun’s UV rays can cause paint to fade over time, so it’s important not to leave your cars out in direct sunlight for long periods of time. If possible, try to keep them indoors where they won’t be exposed to too much light or heat. Alternatively, if you do need to store them outdoors (or even in an unheated garage), make sure they’re kept away from windows so that they won’t be directly hit by sunlight. If possible, cover them with some kind of protective material such as bubble wrap or foam padding when storing them outdoors so that they won’t be damaged by rain or snow either.


Displaying, cleaning, and maintaining a collector’s model car collection is as much dependent on personal taste as choosing the cars to show. Following these simple steps will hopefully keep your diecast memorabilia in excellent condition and allow you to continue to enjoy your collection.

Maintaining the shine of your collectibles just adds to the thrill of growing your collection; and with the right tips, you can certainly have more fun with this hobby. Consider the ideas mentioned here as you keep your diecast car collection in good condition.
