How to Remove Candle Wax From a Wool Sweater

Candle wax on a wool sweater is really two problems: the solid wax caught in the knit, and the colored dye or soot that the wax carried with it. Wool makes both trickier, because it felts and shrinks with heat and agitation, its fibers hold wax in a way smooth fabric does not, and many wool knits are dry-clean-only. Done carefully, though, most dripped wax comes out at home.

Let the wax harden completely

Do not try to wipe or pick at soft wax; you will smear it deeper into the knit and spread the stain. Let it cool and set hard, and speed that up by putting the sweater in the freezer for 30 minutes or holding a bag of ice against the wax.

Brittle, cold wax cracks and lifts instead of smearing. Once it is hard, flex the fabric gently and pick off the large pieces with your fingers or the dull edge of a spoon, working with the knit rather than digging across it.

The iron-and-paper-towel method

For the wax left down in the fibers, place a plain white paper towel or a piece of a brown paper bag over the spot, and a second one underneath it if you can get to the back. Set an iron to a low wool setting with no steam, and press, do not slide, the iron onto the paper for a few seconds at a time.

The warmth melts the wax, and the paper wicks it up. Move to a clean section of paper and repeat until no more wax transfers. Keep the iron moving off the spot between presses so the wool never gets hot enough to scorch or felt, and never touch the iron directly to the knit.

Test the heat first on a hidden area

Some wool blends, and anything with elastane or a novelty yarn, cannot take even a low iron. Before you press the stain, test the iron-through-paper method on an inside seam or the hem for a few seconds and check that the knit does not flatten, shine, or shrink.

If the test area changes at all, skip the iron and take the sweater to a dry cleaner with the wax pointed out.

Dealing with the color left behind

Dyed candles and sooty wicks leave a tint or a grey shadow after the wax itself is gone. On a wool sweater you cannot use hot water or oxygen bleach to clear it. Dab the mark with a cloth barely dampened with a wool-safe detergent or a solvent-based stain remover labeled safe for wool, working from the outside in, then blot with a clean damp cloth.

Test any product on a hidden area first. A faint remaining shadow on a textured knit is often barely visible and is a better outcome than a felted or faded patch.

Washing the sweater afterward

If the care label allows hand washing, wash the whole sweater in cool water with a wool detergent, pressing the suds through gently without wringing or twisting. Rinse in water the same temperature, roll it in a towel to remove water, and dry it flat, reshaping it to size.

Never machine-wash or tumble-dry a wool sweater unless it is specifically labeled superwash or machine-washable. Heat and agitation felt the fibers permanently and can shrink a sweater by several sizes.

Dry-clean-only knits

If the sweater is labeled dry-clean-only, you can still do the freeze-and-pick step to remove the surface wax, which makes the cleaner's job easier, but stop there. Take it in promptly, tell them it is candle wax and mention the candle's color, and do not apply any liquid stain remover first.

Cashmere and other fine animal fibers are especially unforgiving, so those should go straight to a professional after the initial cold pick-off.

Cashmere, blends, and loose knits

Cashmere and other fine animal fibers such as alpaca and angora are more fragile than sheep's wool: the fibers are finer, the knits are looser, and heat felts them faster. On those, do the freeze-and-pick step to lift the surface wax, then stop and take the piece to a dry cleaner rather than risking the iron.

Loose, chunky hand-knits also hold wax deep between the stitches where an iron cannot reach, and open lace patterns snag on paper and cloth. Work slowly, support the knit flat so it does not stretch, and accept that a heavily waxed loose knit may need professional cleaning to get the last of it out.

Testing the iron heat

Before you press the stain, test the iron-through-paper method on an inside seam or the hem. Press for the same few seconds you plan to use on the stain, lift, and check the knit for flattening, a shiny patch, or any shrinkage. Wool blended with elastane, nylon, or acrylic often cannot take even a low iron, and the test is the only way to know before you find out on the visible front of the sweater.

Whatever the fibre, do the freeze-and-pick step first on every wax stain, because it costs nothing and removes the bulk of the wax with no risk. Only the small amount left down in the knit needs heat or solvent, and going in with an iron before you have picked off the hard surface wax just spreads melted wax across a wider area and drives it deeper between the stitches.

After any treatment, reshape the sweater flat to its original measurements while it dries. Wool relaxes when damp and will dry to whatever shape you leave it in, so a sweater dried crumpled or hung on a hanger comes out distorted regardless of how well the wax came out.

Preventing wax on knitwear

Keep candles away from the edge of tables where a sleeve can catch them, trim wicks short so they do not throw soot, and use dripless tapers in holders with wide bases. If wax does land on a sweater, resist touching it while it is warm and let it go fully hard before you start.
