Hi, Anyone know and successfully use an organic leaf cleaner that also provides a bit of shine? My P. Princesses have dull mature leaves, while the newer ones have that healthy sheen. We do have a very dry climate, but I run humidifiers to help with that, but I monitor carefully as a couple have had powdery mildew. I use Arber concentrated products. Is there something else I could be doing to help them keep that healthy glow? Thank you in advance 🪴
