Tailor's chalk is used to mark garments before stitching, helping to correctly position hems, darts and other shaping in the garment. While most tailor's chalks are dry, clay-based products, some tailor's chalks include some amount of wax to create a stronger and more durable line on the fabric. This creates a stain similar to candle wax. Removing waxy tailor's chalk is more difficult than cleaning up chalk stains and somewhat more time consuming.
Set your iron to a low heat setting and allow it to warm.
Place the garment with the stain facing up on the ironing board. Place a clean white towel between layers of the garment, as in the case of a sleeve. Or put it under the garment to protect your ironing board from any waxy residue.
Lay a single layer of clean, unprinted brown paper over the waxy tailor's chalk stain. Press with the warm iron for several seconds, but do not rub or move the iron. Check the paper frequently to see if the waxy stain has lifted from the fabric. Reposition the iron if needed for a larger stain.
Brush the fabric well using a soft brush, particularly if it has a nap or surface texture.
