Living inside, plants can get dusty along with the rest of your belongings. They can get filmy, too, accumulating a coating of substances like grease. The situations isn't optimal for plants since it interferes with respiration and cuts the amount of light that can reach leaves for photosynthesis. The dust and film also give plants a dull appearance, which can be changed by cleaning and polishing. Leaves that take on the best shine are those with thick, smooth vegetation.
Dampen the cloth or sponge.
Wipe both sides of each leaf with the cloth or sponge, supporting the leaf as you clean by placing a hand behind it. Alternately, sandwich each leaf between two cloths to clean.
Rub the top side of each leaf gently with the cheesecloth to buff and bring out shine.
Clean the leaves one to two times per month, depending on how quickly they get dusty, and polish as needed. One of the cleanings can be a gentle shower with barely warm water.
Dust leaves gently between cleanings/polishings with the feather duster.
Spray the feather duster's feathers with rubbing alcohol. This will purge the duster of any pests the duster picked up.
Use a commercial polisher on the leaves according to directions, if desired, but only in rare instances--say, when hosting a party. Polishing agents block a plant's natural processes, damaging health.
Clean plants free of commercial polish as soon as possible.
