Candle wax on fabric looks like a disaster and is one of the easier stains to deal with, provided you do the two steps in the right order and resist the urge to attack it while it is still soft.
Candle wax on fabric is really three problems
A wax spill is two stains occupying the same place, and they need opposite treatments.
The first is the wax itself, a solid at room temperature that has flowed into the weave and set there. It is not dissolved in the fabric, it is mechanically locked into it, which is good news because mechanical problems have mechanical solutions.
The second is dye. Coloured candles carry pigment, and that pigment behaves like any other dye stain. Removing all the wax can leave a coloured shadow exactly where the wax was, and people are often surprised by this because the wax looked like the whole problem.
Scented candles add a third element, fragrance oil, which is a light grease stain.
Deal with them in order: wax, then dye, then oil. Doing it out of order sets the later one.
Let the candle wax harden first
This is the step people skip because the instinct is to act immediately.
Wet wax smears. Anything you do to soft wax spreads it across a wider area and pushes it deeper into the weave, which turns a small hard problem into a large soft one.
Let it set completely. If you are impatient, put the item in a freezer for twenty minutes, or press a bag of ice against the spot. Frozen wax becomes brittle and separates from the fibre readily.
Then flex the fabric and crack the wax. Most of it will break away in pieces.
Scrape the rest with something blunt, a spoon edge or a plastic card, working with the weave rather than across it. Never a knife blade, which cuts fibres.
The iron and paper method
This is the step that removes the wax still in the weave, and it works remarkably well.
Lay the fabric on a hard flat surface with a clean towel underneath.
Put a piece of plain brown paper, a paper bag, or several layers of paper towel over the wax. Never newspaper, whose ink transfers under heat.
Set the iron to a low or medium heat with no steam. Steam drives wax further in.
Press the iron on the paper for a few seconds and lift. The heat melts the wax and the paper absorbs it by capillary action.
Move to a clean section of paper and repeat. This is the important detail: a saturated patch of paper puts wax back into the fabric. Keep shifting to clean paper until no more grease shows on it.
Check the fabric can take the heat first. Synthetics melt at temperatures well below what wax needs, so test on a seam.
The dye that is left behind
Once the wax is gone, look at the fabric in good light. A coloured shadow means pigment.
Treat it as an ordinary dye stain. Soak in cool water with oxygen bleach for several hours, which is safe on colours and breaks pigment down.
For white cotton and linen, a longer soak or a direct paste works harder.
Do not use heat on the dye stage, and do not put the item in a dryer until the colour is gone, because heat sets pigment the same way it sets any dye.
The grease ring
Scented candles and some waxes leave a faint translucent ring after the colour has gone.
Work a small amount of dish soap into it, leave it fifteen minutes, and wash warm. Dish soap is built for exactly this and it outperforms laundry detergent on a small oil mark.
Wash with an enzyme detergent afterwards, which handles what the dish soap loosened.
What not to do
Do not pick at soft wax with your fingers, which presses it in.
Do not pour hot water on it, which melts the wax and carries it through to a wider area.
Do not use a hair dryer, which melts wax with nothing there to absorb it.
Do not use newspaper under the iron.
Do not put the item in a dryer at any point until every stage is finished, because heat sets both dye and oil.
Carpet, upholstery, and candle holders
On carpet, freeze and crack the same way, then use the paper and iron method with the iron held lightly, since carpet backing does not like sustained heat.
On upholstery, test the heat on a hidden area first, since many upholstery fabrics are synthetic.
For glass and metal holders, freezing works on its own. Twenty minutes in a freezer and the wax lifts out in one piece with a gentle push.
The Aurora part
Two local conditions work in your favour here, which is unusual for a stain.
Colorado winters mean candles get used heavily from October through March, and they also mean cold is readily available. A garage or a back step at a Front Range winter temperature hardens wax faster and more thoroughly than a domestic freezer, which makes the crack-and-scrape step far more effective. Take the tablecloth outside for ten minutes before touching it.
The very dry air here is the second advantage, and it applies to the iron stage. Low humidity means the paper stays dry and absorbent rather than going limp, and dry paper wicks melted wax considerably better. The same trick is noticeably less effective in a humid climate.
Hard water is the local complication, and it shows up at the dye stage. Minerals bind with pigment and with oxygen bleach both, so a soak here runs at lower effective strength. Half a cup of washing soda in the soak water fixes it, and it is the difference between a shadow fading and disappearing.
Where a whole cloth gets treated
Table linen is the usual victim, and a large cloth needs to soak flat and rinse in real water volume. Balled up in a small drum, the treated area sits against itself and the loosened pigment redeposits.
The machines at our self-service laundry on East Mississippi Avenue have the drum capacity for a full tablecloth to move freely and the water volume to rinse it properly.
Our machines and the store are cleaned daily.
Our wash-dry-fold service covers the everyday laundry.
If you want a second opinion on any stain, The American Cleaning Institute publishes a stain removal guide that is a useful cross-check.
The short version
Candle wax on fabric is three stains in one: wax, dye, and oil, and they must be dealt with in that order. Let the wax harden completely, or freeze it, then crack and scrape it away with something blunt. Melt what remains through plain brown paper with a warm dry iron, moving to clean paper each time so the wax is absorbed rather than returned. Treat any coloured shadow as a dye stain with an oxygen bleach soak, and lift a grease ring with dish soap. Never use hot water, a hair dryer, newspaper, or a dryer before every stage is finished.
