I posted this to my LJ last night
And today someone suggested I post it here: You know those foaming soaps? You push on the pump handle and foam comes out? And you actually use a lot less soap than you would if you were using the other sort of liquid? Well, if you've been holding off buying one because they are more expensive than whatever liquid soap you buy, hold off no longer. One basic investment will set you up for a long time. Pick the soap and use it. Use it up. And when the bottle is empty, take the pump off, and fill the bottle halfway with your favorite liquid soap. Then fill the rest with water, replace the pump, give it a little shake, and voila, you've just made foaming soap! This works for hand soap or dish soap. But don't try to do it with undiluted soap because it won't work. It has to be thin or it won't foam. So once you've used up the really expensive soap, the rest is way cheaper. Not only do you use less soap when you wash, but the soap is only half strength to begin with. It really is a money-saver.
