"Q... orchid leaves have a sticky residue and bumps... have tried alcohol 
with a water rinse without success...

A. The orchid has scale, and the sticky substance is sooty mold. If you 
control the scale and sooty mold, the sticky leaves will disappear. Put the 
orchid in a separate room so the scale cannot spread to other plants. Dunk 
it in a bucket of soapy water [which concentration ?], leave it there for 
five minutes and then rinse it off with water. Repeat the treatment in 
seven to 10 days to kill hatching eggs."
