Comforters not only give a more versatile look to your bed and bedroom, they protect your down comforter from stains. You can and should regularly launder some types of down comforters, but the laundering process might not remove the stains on the comforter and dry cleaning the down can be expensive. Avoid this by spot cleaning marker stains as soon as you notice them. Don't put off the stain removal process, as the stain will set into the fabric and might be impossible to remove.
Things You'll Need
Blot rubbing alcohol directly onto the stain with a clean, white cloth. Do not rub the stain vigorously as this will spread the marker stain and make it more apparent. Continue this process until the stain no longer transfers to the cloth.
Spray WD-40 directly onto the stain. Let it sit for five minutes.
Scrub the stain gently with a toothbrush, working from the outside of the marker stain toward the inside to make sure it doesn't spread.
Dab acetone onto the stain if you can still see it. Work until you remove all of it.
Apply a dollop of toothpaste to the stain if it is still visible.
Brush the toothpaste into the down until the stain is gone.
Blot the area with a water-soaked cloth to remove the cleaning solution residue.
Dry the comforter completely.
