this is the third time washing my schefflera to get all the white stuff off which i assume is pesticide and yet once it drys, white stuff is still there to be seen. how many times did you have to do this before it was clean? i don't have a hose or anything like that to wash the leaves so i am using my mistking to wet them and then rubbing each leaf with my fingers. it's a bit aggravating as i feel like i am getting nowhere but i refuse to stop until the plant is safe enough for my cham. any help is greatly appreciated.
