If you go through a lot of paper towels, you could be saving a ton of money per year by going with something more durable and washable.
Specifically, use rags to clean up spills, polish furniture, or wherever else you use paper towels in your house. Stores such as The Home Depot sell boxes of rags at pennies a rag that will save you considerably (and save a few trees) in the cost of paper towels. At this writing, you can pick up a box of 200 Xtreme Rags for just under $10 at the link below. Compare that to what you’re spending on paper towels in a month, and you can see that the savings will quickly add up.
