Well, yes, it will be greasier than using normal soap. I keep a separate wash cloth for the cream and another for normal soap. Just put a bit on the wash cloth, rub over the area, then rinse the cloth and use it to wipe away the excess. It will leave the area lightly greasy, but nothing major.
If you can't control it with Aqueous Cream, you may want to return to your doctor. Unless of course the herb ladies have other suggestions.
