If your kitchen sink is smelling less than fresh, sweeten it by cleaning with natural products. Eco-friendly, natural products such as vinegar and baking soda will clean and deodorise smelly sink drains. Replacing chemical cleaning products with natural ones will be easier on the environmental and on your nose. Deodorise your sink drain once a week, or more often as the need arises.
Kill any bacteria that may be lurking in the sink by flushing the drain with boiling water. Boil a large kettle of water. Pour the hot water down the drain to kill germs and loosen any food particles that may be stuck inside the drain. Wear rubber gloves to protect your hands from the boiling water.
Measure 1 tsp of baking soda, a natural deodoriser, and sprinkle it into the drain. Run hot water from the tap for 10 seconds to send the baking soda down into the drain pipes.
Pour 1 cup of distilled white vinegar down the drain to deeply clean and disinfect the drain; the vinegar will also help remove any foul odours that still may be lingering.
Allow the vinegar to rest in the drain for 20 minutes, then turn on the hot tap water to flush the vinegar from the drain.
Finally, pour 1 cup of fresh lemon juice down the drain to give the pipes a clean, sweet scent. After 15 minutes, rinse the lemon juice down the drain with hot tap water.
