purpleinopp, they arrived here when I traded with some folks in OR. They stated that they have this all over their eppies and I set the plants aside but somehow several around it got it. The next year most of ours had it. No one here could tell me what it was or how to handle it. So I just started playing with assorted products and the rubbing alcohol I use to clean the clivia's water stains and it worked.
