In an article on msn.com recently, a journalist researched the true savings for washing Ziploc bags. The outcome: it’s not worth it.
Now, you might be surprised to hear me say that, being that I try to live a green life and I am One Cheap Momma. But ultimately, the savings are too small, and as the author says, “If you have strong environmental standards, why are you using Ziplocs in the first place? Use some heavy-duty reusable containers.”
You could either use 206 new Ziploc sandwich bags at a cost of $3.50 or you could use 26 new sandwich bags at a cost of 44 cents, wash each one seven times in the dishwasher (at a cost of 0.9 cent per wash, a total of $1.64), and spend an hour doing it. Your total savings for an hour of washing Ziploc sandwich bags is $1.42.
Given the multitude of things a person can do for an hour to earn a return better than $1.42, to spend your time washing Ziploc sandwich bags just to save that small amount is a true waste of time. The moral of the story is this: Washing Ziploc sandwich bags is not an effective use of your time.
