1. Use A Door Mat: It doesn't matter if you live in an apartment building or have your own front porch, an outside doormat is the first line of defense against dirt coming into your home.
2. Remove Shoes When Entering: In many homes around the world, this is already a very common practice, but removing your shoes when you enter your home leaves the rest of the outside world there, instead of tracking it through the home. If you don't have room to have a seating area, try a shoe rack or even a few carpet squares on the floor of your coat closet to help catch the dust that might fall.
3. Step Away From The Plug In Air Fresheners: Although it can be tempting to make the first smell when you walk into your home a signature thing, all it really does is bombard the senses of others. You want the first impression of your home to be fresh, clean and airy not "lilac-summer meadow-cranberry-fresh baked cookies!" Try instead to wipe down baseboards and walls with a light vinegar and water solution to keep them clean and vacuum carpets with a little scented baking soda if you really prefer the extra boost.
4. Moisture Be Gone! One of the biggest culprits of smells is the presence of moisture. Try keeping things outside or on a balcony if possible until dry (umbrellas, shoes, dog leashes). If that isn't an option, try keeping a small desk-size fan tucked out of the way. Once turned on it can help accelerate the rate at which things dry, keeping the musky-mildewy smells at bay.
5. Remember The Little Things: There might not be much in your entryway, but in this small space, cleaning the details can make all the difference in the world. Using an all-purpose green cleaner to tackle doorknobs, door jambs, lamps and more is a great way to go. Likewise, whip up a quick vinegar and water solution to tackle windows, mirrors and doors that might be fitted with glass. A clean entrance is a light, bright and reflective one, so don't forget the finishing touches!
