Dyeing your comforter is an inexpensive way to help make it look new and vibrant. One huge advantage of using fabric dye is that it can be purchased at almost any retail store. In addition to fabric dye, all you need is about an hour of time and some basic cleaning supplies for the cleanup process and you're ready to get started.
Dye Your Comforter
Wash the comforter to remove any stains. Your comforter should be clean and stain-free before dyeing.
Fill a tub with 3 gallons of hot water. Add the fabric dye to the hot water. If you are using liquid fabric dye, add four ounces for each pound of fabric. If you are using powder fabric dye, add one 1/8-ounce packet for each pound of fabric. If directions are different for the dye brand you purchase, follow directions on the dye package instead. Pre-dissolve the powder fabric dye in two cups of water before pouring it into the tub.
Stir the water in the tub to evenly distribute the fabric dye. Wet the comforter thoroughly with clean hot water before placing it into the tub. Wring the excess water from the comforter.
Place the damp comforter into the tub. Agitate the comforter using a wooden stick. Stir the comforter around in the tub for up to 30 minutes, depending on how deep a shade you want to dye the comforter.
Drain the water from the tub. Rinse the comforter using warm water. Gradually expose the comforter to cooler water until the water rinses out clear.
Wash the comforter by itself using mild detergent. Set your washing machine to use warm washing water and cold rinsing water. Dry the comforter using a machine dryer or hang it outside to air dry.
Remove Stains From the Tub
Fill the tub with warm water until the water reaches the stain line. Add white vinegar or chlorine bleach to the tub. Use approximately 1 cup for every gallon of water.
Allow this cleaning solution to soak in the tub for 15 minutes. Drain the tub.
Mix 1 ounce of chlorine bleach and 1 cup baking soda until it forms a paste. Scrub any remaining stains with a toothbrush using this whitening paste.
