Another reason why many business owners prefer to use plastic display cases is because it is easy to clean and maintain. Sure, these cases gather dust and stains over time, especially when they are exposed to outside elements (such as when you use them in outdoor exhibits or outside your shop), these can be easily remedied by simple dusting or wiping. Plastic display cases don’t normally have issues with food and other types of stains, just make sure that you wipe them immediately. You can also use a multi-purpose cleaner in order to better remove any stains. When wiping, avoid using coarse or gritty cloth since this may leave scratch marks on your plastic display case. If you see any scratches though and you’d like to get rid of them, you can have a professional sand and polish them back to their original state. Please note that sanding is best left to the hands of a pro, since you may do more harm than good to your plastic display case if you’re not aware of the proper way to perform the procedure or lack the necessary tools for the job – and no, a diamond polisher, which is a factory used equipment, is not what you need.
