method all purpose is a powerful surface cleaner made with naturally-derived surfactants. It works by absorbing dirt rather than chemically degrading it. And method is biodegradable so you can clean your home without flushing super-toxic chemicals down the drain into our rivers, lakes and oceans. We're against that. Dirty doesn't have to roll downhill. We think clean smells more like lavender than ammonia or bleach, so we have added lavender oil.
