Baking soda can be used for more than baking or keeping your fridge smelling fresh.  Use baking soda the next time you need to remove stains from sinks, toilets or plastics like toys or outdoor furniture.  Apply a layer of baking soda and scrub with a damp sponge. 

Baking soda can also be used on walls to remove dirt and even crayon marks.  Make a paste with water and baking soda then apply to an old toothbrush and scrub gently on the wall.  Wipe clean with a damp sponge.
