If you have ever slid hot candle wax to your trash disposal, then you probably knew it had been a mistake as soon as you did it. The wax collects in the outlet holes of this disposal and effectively blocks the drain. You can eliminate it using intense heat or extreme cold.
Melt the Wax
Boiling water will melt the wax, however, the trick is to use enough of it to give it time to work. Instead of pouring pots filled with boiling water down the sink, put in the drain stopper and fill the sink with boiling water. It will melt any wax that’s collected on the sink itself, and if you remove the stopper using a long-handled employ, enough water will flow through the trash disposal to melt the wax and then sweep it down the drain.
Pouring crushed ice down the drain hardens the wax so it may break into little pieces when you run the garbage disposal. Make sure you use enough ice to fill out the disposal. Neither ice nor boiling water is sure to work, particularly if the wax has made it past the garbage disposal to the P-trap. In that situation, removing the trap and gently cutting out the wax is probably your only alternative.
