1. Pour vinegar into a wide-mouth container or bowl and set on the kitchen countertop to use while cooking. It will absorb some of the odor. Use more than one container and set in other rooms if the odor is persistent. Or boil for 10 minutes once done cooking (however it leave a vinegar odor if you do this approach).
2. Boil cut pieces of citrus on the stove top. Reduce the heat to a simmer once it reaches the boiling stage. Lemon, orange and lime produce a pleasing aroma. You can also add nutmeg or cinnamon. Check the water level periodically and add more water as needed.
3. Sprinkle baking soda on carpets and vacuum after 30 minutes. Or scrub baking soda on the cutting board and areas of use with the food.
4. Break charcoal into small pieces. Place the charcoal inside a newspaper and break apart with a hammer. Pour the charcoal into a bowl and place where needed. Do not use charcoal that has lighter fluid manufactured into it.
5. Use unscented kitty litter in bowls. You can place in decorative bowls, and no one will be aware of their real purpose.
6. Most important is air circulation. Open some windows or use a fan or air conditioner to move air around. You can also put some essential oil (lavendar is nice smelling) on a piece of cloth and hang it on a vent so the air circulates and smells better.
7. Burn a candle or two near you on the counter while you cut onions. The flame can absorb some of the onion gases that are released when you cut them. And keep the onions cool in the fridge before you cut, so the odor is less than if you were to store them in a cupboard.
