Clean. Ok, I know what you're thinking. This is probably something you do everyday. But what about the deeper cleaning? Think spring cleaning, but getting it done before you want to spend all of your time outdoors. Baseboards, cabinets, windows (at least the insides), are typically things we put off throughout the year, but being trapped with no place to go is the perfect opportunity to get them done. Put on your favorite jam and go to town. I always feel like I can breathe better when the house is squeaky clean.
