Leaf Shine for plants are commercial products that clean and shine the leaves of indoor plants. Always read the instructions thoroughly and test any houseplant cleaner on one or two leaves to be sure it won’t damage the plant. Move the plant out of the sun before using, be sure the soil is damp, and avoid getting plant cleaners on floors, tables, and walls. These products usually dissolve dust, mineral deposits, water stains, and then dry to a natural shine. Do not use on furry leaf plants such as African Violets and Begonias, nor on Palms. Never use milk or mayonnaise to clean plants.
