Garbage disposal not working like it used to? 🧊

Drop a handful of ice cubes into your garbage disposal, run cold water and turn it on. The ice can help knock away built-up food residue and keep your disposal working efficiently.

Still having trouble? A clog or another plumbing issue could be the culprit.

Do you run hot water down your clogged kitchen drain? There may be a better solution. 🚰

Hot water can melt grease temporarily, but as it cools farther down your pipes, that grease can stick and contribute to bigger clogs later. Try running cold cater instead!
