During holidays or birthday celebrations, melted wax from candles can find their way onto a holding dish. If that dish gets placed in the dishwasher, the mixture of hot water and steam could melt the wax just enough to leave a stain on your appliance. Removing wax stains from the interior of a dishwasher requires chipping off the cooled wax and then warming up the residue in order to wipe the stain away completely.
Remove the dishwasher racks or utensil carrier so that you can access the wax.
Place three pieces of ice in a plastic bag.
Place the plastic bag on the wax stain to harden it completely. This will make the wax more brittle and easier to remove.
Wedge the edge of a plastic spoon under the piece of wax. Don't use metal because it can scratch the dishwasher.
Press the spoon against the wax to chip away at the stain.
Soak a cloth in hot water. Wear rubber gloves to protect your skin from the heat.
Rub the cloth over the wax to remove any remaining residue.
Place the racks or utensil carrier back into the dishwasher.
