Stinky disposal, Smelly Drains, Stinky sinks
1. Hot water and dish soap for stinky drains.
Start by letting a sink full of hot, soapy water flush through the garbage disposal while it's running. This is the first step, and may do the trick!
Put a stopper in the sink and fill it with several inches of hot water. Add a squirt of dish soap. Turn on the disposal and unplug the sink to let the water flush through. This is different than simply running the tap like we usually do since the disposal will actually fill with water.
2. Ice cubes, coarse salt, and lemons peels for smelly drains.
If you're still getting a funky smell, the next step is to make sure the disposal blades are clean and clear of lingering gunky food particles. The combination of ice cubes, coarse salt, and lemon is a three-punch cleaning wonder.
We threw a few ice cubes and a handful of kosher salt down the disposal. The ice helps knock food off the grinder while the salt scrubs the sides. For good measure, we repeated the flushing and then ground up a few lemon peels for freshness. Voila! This seemed to do the trick and we haven't noticed any odors since.
3. Boiling water. To keep stinky smelly drains clean
The simple power of hot water is not to be underestimated. If you've just boiled water for something — a bit of pasta or a pot of tea, for example — don't let it cool off on the stove. Instead, pour it down the sink. This may be enough to take care of milder drain smells. If not, keep going down this list to amp up the cleaning power, but as you'll see, every tip ends with a good hot water flush!
