Something This Way.. Stinks: Tips to Clean a Smelly Disposal.
Sometimes, a quick hack for your home comes from an unlikely source, like say, TikTok... (well, in my case it was my mother), but a quick internet search will show you that sites from TikTok to Better Homes and Gardens to Lifehacker recommend this method. Forget lemons and costly cleaners. Super cheap salt works the best. Yes, that salt. Good old-fashioned Kosher salt. Here’s how it works:
it a stopper into the sink, and fill with hot water and a squirt of dish detergent.
Turn on the disposal and let the soapy water drain, pushing gunk down the drain with it.
Throw a handful of ice cubes and a handful of large-grain salt, such as Kosher, down the drain and run the disposal.
Flush with water, and you’ve got a clean disposal.
Voila! A fresh-smelling drain!
If for some reason this hack doesn't solve your issue, there might be something else causing the clog, so check out https://www.bobvila.com/articles/how-to-clean-a-garbage-disposal/ for additional tips by the Pro himself, Bob Vila.
