If you have a cedar closet, you know how great it is for keeping your clothes smelling fresh. But over time, even cedar closets can start to smell musty. Here are a few tips for keeping your cedar closet smelling fresh: 1. Keep it clean. Just like any other closet, a cedar closet needs to be kept clean. Dust and dirt can build up and make it harder for the cedar to do its job. Vacuum or sweep the floor of your closet regularly and dust any surfaces. 2. Ventilate it. Cedar closets work best when they're well-ventilated. Make sure there's good airflow in your closet by opening the door or a window when you can. 3. Refresh the cedar. Over time, the cedar in your closet can lose its freshness. You can refresh it by lightly sanding it with fine-grit sandpaper. 4. Add cedar balls. Cedar balls are a great way to keep your closet smelling fresh. You can find them at most home stores. Just add a few to your closet and they'll help absorb any odors.
