33 Prepper Uses for Aluminum Foil


33 Prepper Uses for Aluminum FoilAluminum foil (often erroneously referred to as tin foil) is possibly the most versatile item in your kitchen. I could probably list 100 different uses for aluminum foil, but for this post I’m going to focus on uses that might interest preppers and homesteaders.

If you don’t have any aluminum foil yet, be sure to get some. I also recommend getting a small roll for your bug out bag. Note: In places where I mention reflecting light or heat, be sure to use the shiny side (yes, one side is shinier than the other). Now on to the list.

1. Help Seedlings

Line a box with foil, poke drainage holes in the bottom, fill halfway with soil, plant your seeds, and place it on a windowsill. The sunlight reflecting off the surfaces will help the plant grow.

2. Grow Plants

In the same way, you can use foil to reflect more sunlight onto your plants so they grow better. Lay foil beneath your plants, or tape foil to a surface and place it next to your plants.

3. Keep Pests Away

If you have a garden, hang strips of foil around it to deter birds and small animals. The shiny surfaces and metallic sounds will make them wary and keep some of them from eating your plants.

4. Keep Birds Away

In the same way, foil can be used to keep birds away from fruit trees. Just use some fishing line to hang strips from the branches. The light reflecting off the surfaces will scare birds away.

5. Protect Trees

During the winter, bugs and rodents often munch on tree bark. To protect your trees, wrap a couple layers of foil around the trunk. This can make a significant difference. Remove the foil in the spring.

6. Catch Fish

When fishing, wrap a small square of tin foil around the hook or weights. The light reflecting off the foil will lure more fish.

7. Start a Fire

You can use a strip of foil, some cotton, and a battery to make a flame. Watch this video to learn how. It also makes a good surface for starting a fire with petroleum jelly and cotton.

8. Protect Your Hands

If you’re holding a candle, you don’t want hot wax dripping on you. Tear a hole in the center of a thick layer of foil, push the candle through, and shape the foil into a bowl to catch the wax.

9. Make Char Cloth

Char cloth ignites with just a single spark, so it’s very useful for starting fires. Watch this video to learn how to make char cloth using aluminum foil.

10. Keep Things Dry

Wrap matches, tinder, food, or anything small that needs to be kept dry in tin foil. As long as you wrap it multiple times, it should work.

11. Fry Some Food

Find a branch that forks, stretch some foil across it, and wrap the foil around the branches to make a pan. As long as the food is not too heavy, you can hold this makeshift pan over a fire.

12. Cook Some Food

Another method is to wrap thinly sliced meat, veggies, and some spices in several sheets of foil and place it on some hot coals. After a little while you’ll have a nice, hot meal.

13. Block Wind

Protect flames from wind using a wall of aluminum foil. If you have a small fire or burner stove, this could be very useful.

14. Clean Your Grill

After using your grill, completely cover the grate with heavy-duty foil. The heat will be unable to escape, and it will work like a self-cleaning oven. Then ball up the foil and scrub the grate with it.

15. Clean Up Ashes

Place two layers of heavy-duty foil on the bottom of your grill or fireplace before you start a fire. Once you’re done with it and the ashes have cooled off, simply wrap them in the foil and throw them away.

16. Make a Solar Oven

With aluminum foil, cardboard, and a few other supplies, you can make a solar oven. This article explains how to construct and use one.

17. Catch Drippings

Place foil along the bottom of your oven before baking something. It will catch anything that boils over and spills, keeping your oven clean. Remove the foil each time.

18. Collect Rainwater

Aluminum foil can also be fashioned into a large pan to collect rainwater. The larger the surface area, the more water you’ll collect.

19. Boil Water

Dig a hole in the ground, shape the foil to fit the hole, and fill with water. Put some rocks in a fire, then use tongs to transfer the rocks to the water. It will start boiling right away.

20. Make a Funnel

Push a stick through several layers of foil, then shape the foil into a funnel. Remove the stick, and use the hole you made as the spout.

21. Make Plateware

You can make more than just bowls and funnels. You could also shape the foil into plates, cups, and utensils if you don’t have any real plate ware.

22. Scrub Pots and Pans

Make a ball of foil and use it to scrub dirty pots and pans. This can be as effective as regular scrubbing pads, but don’t use foil on non-stick surfaces as it can damage them.

23. Remove Rust

Crumpled some aluminum foil into a ball and use it to scrub rust off of metal. It works even better if you dip it in Coca-Cola first.

24. Protect Soap

Put a layer of foil beneath a bar of soap to keep the bottom from turning into mush. If you do this, your soap will last a long longer.

25. Fix Loose Batteries

Sometimes the springs in old flashlights and radios can get too loose to hold batteries in place. To fix this, fold up a small piece of foil and place it between the battery and the spring.

26. Protect Electronics

It is possible to make a Faraday cage using aluminum foil. A Faraday cage can protect your electronics from an EMP (electromagnetic pulse). Read this article for more information.

27. Enhance Antennas

If you have an old radio or TV with a traditional antenna, you can wrap a ball of foil around the ends to improve the reception. It will only help a little, but it might be enough.

28. Signal for Help

If you’re stranded in the middle of nowhere, you could use the reflective surface to signal a plane or vehicle in the distance for help.

29. Sharpen Scissors

Smooth out a sheet of foil and fold it in half several times, then start cutting. After a short while, your scissors will be nice and sharp.

30. Reflect Heat

In the summer you can put foil on windows to reflect heat from the sun. In the winter you can put foil on the wall behind the radiator to reflect heat back into the room.

31. Find Your Way At Night

Hang foil from trees at eye level along a trail that you plan on following at night. The foil will reflect light from your flashlight and make it easier to stay on the path.

32. Stay Dry While You Sleep

Put a layer of foil beneath your sleeping bag to prevent moisture from getting in while you’re sleeping.

33. Make a Tin Foil Hat

Okay, I know this one is kind of silly, but there is a scientific basis for it.

    I stopped using aluminum foil, as well as aluminum pots a pans and tableware, years ago to reduce sources of aluminum contamination. I can see that there are suggestions for using it without direct contact with food, which I may try.
