How To Sharpen Garbage Disposal Blades

Just like your kitchen knives, your garbage disposal blades can dull over time from use.

To sharpen the blades, combine table salt and coarse cleanser (we like Bar Keeper’s Friend), shove the mixture down past the baffle (yes, that rubber ruffle-y thing has a name!) and run the disposal without any water. When that’s finished, run water with the disposal like normal and rinse away the residue.

The coarse mixture should sharpen your blades. Another tip: Always run cold, not warm, water when running your disposal. Cold water hardens greasy substances, which makes them easier to grind, and keeps grease from sticking to the drain lines.
