If your linens have been stored away in a location that ended up wet or moist, you may discover that you have mildew stains on your bed or table linens. As long as the mould hasn't eaten through your fabric, there's hope for restoring your linens to their pre-mildew condition. Use natural resources and a few simple supplies found in your kitchen to remove mildew from your household linens.
Brush mildew off your linens using a clean, unused paint brush. Do this outside so the mildew doesn't land and grow elsewhere in your home.
Spread the linens out in the sun and allow them to air out for an hour or two. This may be all that's needed if the mildew was barely there.
Wash or dry clean the linens according to directions, then allow them to dry or sit in the sun.
Mix equal parts of lemon juice and table salt in a bowl. Pour the mixture onto any remains of the mildew stain and rub it into the stain by rubbing the fabric together. Spread the linens in the sun, allowing the mixture to soak into the fabric. Check for progress every 15 minutes. When the stain is gone, rinse well with water, then wash according to care instructions.
Store linens in an airtight container where they will be free from humidity or moisture.
Mildew grows and spreads, so check other linens stored in the same area as the ones with mildew stains.
