When I want to clean my ficus tree, I take it to the bath room, lay a towel on the floor of the tub, and cover the container and the area around the trunk of the tree with plastic. I use my shower sprayer, get some cheap shampoo and pour it over the leaves, lather, and spray off. This does the trick. Then I let it sit for about a hour until it quits dripping, remove the tree from the tub onto a dry towel and let it sit for awhile. Sometimes I let it sit over night or until later in the day and wow, shiny leaves again, and smells good too. LOL
