Honeycomb cellular shades are both durable and functional. To keep your honeycomb cellular shades looking like new, we at www.blindsanddrapery.com recommend regular dusting with a feather duster. You can also use the brush attachment of your vacuum or even blow off dust with a can of compressed air. If you need to deal with stains, blot with a damp sponge and a very mild soap. If this does not take out the stain, you can remove the honeycomb cellular from its mounting bracket and soak it in warm, mild soapy water. Be very careful! Make sure to test the soap on a discreet corner first and rinse thoroughly. When you are ready to put your honeycomb cellular shade back in the window, make sure to raise the shade tightly to re-crease the pleats.
