5) Cinnamon solution
This recipe will provide you with not only an anti-mold but also a great room deodorizer. Mix 200 ml of water, 200 ml of apple cider vinegar, 15 drops of cinnamon essential oil and 10 drops of manuka essential oil (very similar to tea tree oil) in a spray bottle. Spray the solution on the mildew stains, leave to swirl, then dry and air the room.
