Lampshades are easily overlooked when cleaning your home, but they do get dirty and stained over time. Cleaning methods vary depending on what the shade is made of, but there are some basic procedures for cleaning shades and removing spots or stains. Remember that lampshades are exposed to heat from lightbulbs, and, over time, this can cause yellowish discoloration in the lampshade. You will not be able to remove that type of discoloration, but you can remove many other stains.
Fill a bathtub with cool water. Add 1 cupful of mild liquid detergent and swish to build up suds.
Place your lampshade in the tub and lift it up and down, swirling it through the water.
Use a soft cleaning brush to rub out any spots or stains. Dip the shade up and down again.
Empty the tub and refill with clean water. Rinse the shade by dipping it up and down and swirling it through the clean water. Repeat this step twice.
Blot the lampshade with a towel until nearly dry, then put it back on the lamp. Turn the lamp on, so light from the bulb will finish drying the shade.
Vacuum the lampshade with a hand vacuum or the small brush attachment on your vacuum cleaner.
Wipe the shade with a microfiber cleaning cloth.
Rub out any remaining spots or stains with a soot- and dirt-removal sponge. You can find these at hardware and home-improvement stores.
Combine 1 tsp. of mild liquid detergent and 1 cup of water in a bowl. Wipe the lampshade with soft cleaning brush dipped in the mixture. Rinse with water.
Dry with a cloth.
Spray furniture polish onto a clean, dry cloth. Wipe to shine.
