Q.Harm to Houseplants From Natural Elimination of Aphids
Last week I sprayed my indoor plants (Clivia, Aloe, Walking stick succulent) with the combination treatment of water, dishwashing liquid and oil in order to get rid of the few aphids I found (brought in by a gift of an African violet).
There has been no trace of aphids since, but the liquid formula is still on the leaves of the Clivia, a very large plant by now. Should I do anything — such as washing the formula off the leaves or leaving the oil and liquid on the plants?

It should not hurt the plant, but if it is unsightly, you can wash it off. Placing the plant in the shower works well for whole plant cleaning.
