How to remove mildew from curtains?

Removing mildew from curtains requires careful handling to prevent fabric damage while effectively eradicating the fungi. Mildew, a surface mold, can cause discoloration and a musty odor. Successful removal depends largely on the fabric type and colorfastness.

Preparation and Pre-Treatment

Before applying any solution, take the curtains down and shake them outdoors to remove loose spores. This prevents them from spreading indoors. Always test your chosen cleaning solution on an inconspicuous spot, like a hem or seam, to ensure it doesn't cause discoloration or damage. Ensure the area is well-ventilated during cleaning.

Cleaning Solutions

For most washable fabrics, a mixture of equal parts white vinegar and water can be effective. Apply, let sit for an hour, then wash. For white or light-colored, bleach-safe fabrics, a dilute bleach solution (1/4 cup bleach per gallon of water) can be used. For delicate fabrics, milder options like hydrogen peroxide (diluted 1:1 with water) or borax paste (borax mixed with a little water) are preferable. Follow with a thorough wash in the hottest water safe for the fabric, and air dry completely in sunlight if possible, as UV rays help kill remaining spores.
