3 Methods to Clean Candle Wax from Sink Drain

Freezing Method

Freezing Method

Step 1: Freeze Water

This allows the candle wax to freeze and makes it easier to remove.

Step 2: Turn on the Garbage Disposal Chute

This allows the candle wax to get crushed in the disposal chute and makes it easier to remove.

Freezing Method Advantage

Pouring broken ice down the drain hardens the wax, causing it to break into little pieces when the garbage disposal is used. Make sure you have enough ice to completely fill the disposal.


When using Freezing Method, you should always be aware that the wax did not reach the P-trap. Because the only way to clean it is to remove the P-trap manually.

Heating or Boiling Method

Heating or Boiling Method

Step 1: Put the Drain Stopper in your Sink

You need to place the drain stopper so that the boiling water would get drained easily.

Step 2: Boil Water

Boiling water helps re-melt the wax and makes it easier to let your drain flow properly.

Step 3: Pour the Boiled Water

Fill the sink in as much boiling water as you can in one shot. This will melt any wax that has been collected on the sink’s surface.

Step 4: Cooking tool or Equipment

To remove the candle wax, use a lengthy tool or cooking equipment. And if the first attempt does not work repeat the procedure again.

Boiling Method Advantage

The wax will melt if you use enough boiling water, the trick is to use enough for it to work. Put the drain stopper and fill the sink with boiling water instead of throwing boiling water down the sink repeatedly.

If you remove the stopper with a long-handled device, enough water will flow through to melt the wax and sweep it down the drain.


When using the Heating method, you can sometimes burn your skin because of the water’s heat and steam. When using this method, you should always keep in mind to always be careful.

Wiping Method

Wiping Method

Step 1: Wipe the Candle Wax

Step 2: Pick at the Candle Wax

Begin wiping the wax away from the edges to prevent it from spreading. Then proceed to the center. Do not rub the liquid wax instead wipe it gently.

If you’re using wax on a mop sink, make sure you’re being careful. These are fixed at a given height and they may fall over, causing harm to your sink.

Wiping Method Advantage

If the wax spill is still fresh and hasn’t solidified, wipe the area with sink paper or paper towels immediately. This method helps when the wax did not harden yet it will be a lot easier to remove.


You can only use the wiping method if the wax did not completely harden yet.

Note: If the Freezing method does not work here are the steps you need to follow. You need to clean your P-trap because there is a chance that the wax is already too deep.

Candle wax often tends to leave behind remains and residues.

Use soapy water or a detergent to clear the residue. Vacuum the rest of the solid bits.
