How to Make Your Bedroom Smell Good
Ideally, your bedroom should be a place of peace and comfort. But if odors build up in your quarters, it’s hard to feel at home. Conventional air fresheners are often full of toxic chemicals that can be harmful to your health when inhaled (phthalates, for example, are thought to be endocrine disruptors in humans and wildlife).   Fortunately, there are plenty of ways to get your bedroom smelling good again without harm to yourself or those around you.
Part One of Three:
Cleaning Your Bedroom Edit
Open your windows. There’s no better air than fresh air; plus, direct sunlight can kill mold and other odor-causing bacteria. Contrary to popular belief, outdoor air can be less toxic than indoor air, where things like lead dust, radon, and other toxins can build up. Open your window(s) once a day for at least five minutes. 
Clean the bed . Wash your sheets and pillowcases once a week, and clean your comforter at least once a season (every three months). Bedding can be odorous if you don’t wash it regularly.
- Instead of making your bed immediately after getting up, pull the sheets down so that the mattress can air out for at least 30 minutes. We release moisture when we sleep, which can dampen the bedding, making it a breeding ground for mold and bacteria.
Wipe down surfaces. Use a microfiber dust rag to trap dust, or consider using the homemade lemon rags for an added fresh scent. Make these dust rags in advance, and use them to dust your bookshelves, window sills, electronics, etc.
- Mix 1 cup (236 ml) water, 1 cup (236 ml) white vinegar, and 1 tablespoon (14 ml) olive oil.
- Soak a few dust rags in the solution. (Old t-shirts, underwear and socks can gain a second life as star cleaners!)
- Wring out the rags so they are damp-dry, and then place them in a glass jar, layering them with the rind of one lemon cut into a few pieces. Close the jar tightly. 
Use a vacuum cleaner with a HEPA filter. After cleaning your room, vacuuming ensures that you have cleaned everything off your floor. Don’t forget the corners, under the bed, upholstered furniture, and even the walls, where dust can accumulate.
- The HEPA filter helps trap allergens like dirt and dust, preventing them from being released into the air.
- Vacuum two to three times a week if possible, and wash out the HEPA filter regularly. 
Apply vinegar to the walls. The walls of your room can trap and store many odors, which vinegar helps to kill. Mix 1/4 cup (60 ml) of vinegar with 2 quarts (2 liters) of water. Dip a sponge or washcloth into the mixture and clean your walls.
- Don’t worry about the smell of the vinegar: it goes away once it dries.
