Arm&Hammer Essentials Multisurface Cleaner
Save some money and the planet with this Arm& Hammer product. Each spray bottle comes with a cartridge of concentrated, plant-based cleaner that you mix with tap water to create a stain-attacking cleaner. When the cleaner runs out, buy a refill cartridge instead of a whole new bottle. Less plastic and less money is a win-win situation.
($9 for refillable bottle and one cartridge; $6 for two-cartridge refill pack, Mass Retailers)
