I'm trying to reduce my disposable plastic bag use, but Ziplocs have become such a part of my routine I find them indispensable. I rewash mine and dry them on the kitchen counter, but some are simply unwashable. Here's how Harmzie uses them:
Can you stand one more Ziploc bag use? I know. They just go on forever! But this one is a re-use. From back in my diapering days – they actually only ended about six months ago but it seems like forevahhhhh! (sorry, didn't mean to gloat) When I had Ziploc bags that were used but too good to toss, i.e. didn't want to use them for food, but they're not slimy, I tossed them in the diaper bag. Whenever there was a #2 "incident" at someone's home who didn't have kids (works for anywhere that doesn't have a diaper garbage – restaurant, grandparents), I used a Ziploc bag to contain the mess & the smell.
This works with Ziploc sandwich bags, too — if they come back home in your child's lunchbox, they're good for packing away used newborn diapers or stowing tiny wet undies or dirty socks.
