1. Waste disposal
Waste disposal can get stinky. Clean them the natural way using baking soda, salt and ice. Full instructions can be found here. Putting lemons or other citrus skins down the waste disposal help keep it smelling fresh. Do it every few days if you can.
2. Kitchen Smells
If the cooking odors are getting a bit much and the kitchen is not well ventilated try simmering vinegar in water while you’re cooking. 1 Tablespoon vinegar in 1 cup water should do it. You can also wipe down smelly chopping boards with a dash of vinegar in warm soapy water.
3. Removing bathroom mold
Almost every bathroom can get a touch of mold. It can be easily removed by mixing one part hydrogen peroxide (3%) with two parts water and spraying on mold spots. Rinse off after one hour. Tough spots may need rubbing with a sponge.
Don’t forget to open windows while you’re working.
