Add Water to Use It Up

Get into the habit of adding water to your nearly empty jars of tomato sauce, soups, etc. to get the last bit out. This also helps with clean up if you are saving the container, as it will remove the otherwise stubborn bits that are hard to reach. (Here are some ideas for what to do with that last bit of spaghetti sauce, for example.)

You can add a bit of water to condiments as well. Part of the reason it's so hard to get out the last bit of ketchup from the container is it is thicker, since evaporation has taken place. Add water to put it back to the right consistency. If you add too much, use it as an ingredient in some recipe.

The last of the shampoo, conditioner, liquid laundry soap and dishwashing soap can be used by adding water. You'll be adding water to these in the process of using them anyway. This way, you can go just a little longer before you have to get a new bottle. I remember reading once that shampoo actually works better when diluted to 50% water.
