Hi bingham, and welcome to ATP. Hope we can help you out here.
So, the plant now has no leaves at all? If it has any leaves left, how about showing us a picture? I also have no clue what a 'plowmanii' might be.
Alcohol is a pretty strong chemical to use on leaves especially if the plant is already in distress. A better choice might have been a mild soapy water solution. about 1/2tsp. to a quart of water. Spray it down or wipe with a paper towel, then rinse off after a while.
