Use a Soap Dish, Save Money

A bar of soap that gets left in standing water dissolves up to 50% faster than soap that's kept dry when not in use. If you have a large family or take tons of baths or showers, you might be purchasing new soap twice as fast as you need to. Use a soap dish (I love the kind with little soft plastic spikes) that keeps the bottom of the soap dry and makes it last noticeably longer.
