For tiny trinkets and knickknacks with small parts that are difficult to clean with a standard household rag, try this handy hint: Slip on a pair of soft (preferably cotton) gardening gloves. Then use your fingers to clean the hard-to-reach nooks and crannies of your collectibles.
This dusting method also works great for office items—a pencil holder, globe, tape dispenser, picture frames, etc. Just run your hands over each item and the gloves collect all of the dust. To get rid of germs in the process of dusting, spritz the cotton gloves with a small amount of antibacterial cleaning solution.
