A long time ago, I posted about a tip from Dr. Sears on The Doctors. By making your own gel ice packs using dish soap you save money, and get basically a medical-grade ice pack for pennies! The soap doesn't solidify so it molds to the shape you need, it gets colder and stays colder longer. Here's how to make your own:
DIY Gel Ice Packs
1. Select a Ziploc bag size of choice (but I would probably not recommend a gallon-sized bag). Double or triple-bag it to protect against leaks over time.
2. Fill it 1/2 to 3/4 full with cheap dish soap (the Dollar Store or Walmart would be a great place to find some).
3. Readers who tried this suggested adding a little bit of rubbing alcohol to the mix too, which helps it stay nice and pliable.
4. Close the bag, making sure to squish all the air out. Freeze it!
5. You could freeze the bag entirely and them vacuum-seal it for added protection if you have one.
I have also heard 3 parts water 1 parts rubbing alcohol works well, too.
Just as any ice pack does, it will wear out over time. But some readers who tried this said it lasted well over a year before they tossed it out and made a new one. Just keep your eye on it. Who wants soap everywhere?? 😉
