The shiny coating might indicate insect feeding on your plant. When sucking insects such as mealybugs and scales feed they can exude a sticky substance called honeydew. It coats the surface of the leaves under the parts of the plants where the insects are feeding. This substance washes off with water. Thoroughly inspect your plant for insects - I think you'll find them. Control the insects and the coating will go away. Not all insect pests can be controlled with all insecticides, and not all insecticides are safe to use on all plants so you'll need to have your plant identified before you can choose the proper insecticide. Good luck with your plant.
