This has got to be the most time consuming part of my hobby, is keeping the leaves dust free. I have seen leaf shine in the stores but know to stay away from it due to the fact that it can clog leaf pores. So is there anything I can use to keep my leaves shinier and dust free for longer that a few days. How do people grow these beautiful plants with deep glossy leaves? A friend of mine told me to wipe the leaves with dish soap, but I am a bit hesitant about trying this as I have never heard of this before. TIPS???
