Thirty Unusual Uses for Aluminum Foil

I love aluminum foil. It's recyclable, it's shiny, and it is super versatile. It can be used to clean, catch, protect, frighten, scrub, lift, soften, shape, grow, fix, sharpen, steam, attach, boost, and polish. We'll get into the specifics in just a moment, but first I would like to share a quick haiku about aluminum foil:

Aluminum* foil
The duct tape of the kitchen
All kinds of useful

Some of the following uses may surprise you. Some may anger you. Others may just leave you thinking, "I knooooow, I totally use it that way every day." Either way, these aluminum foil tips and tricks may just save your life, so settle in, grab a beverage, and position your roll of aluminum foil so you can gaze at it lovingly while I extol its many virtues.



*To those of you who speak British English, the syllabication doesn't quite work here. Aluminum was given an extra i to make it sound like all of the other -ium elements: helium, plutonium, uranium, etc. This is equally correct; I'm just going to use the lazy American disemvowelled version. In the meantime, don't go getting any ideas about platinum. It'd sound weird with an extra i. Say it aloud, "Platinium." That's how aluminium sounds in the colonies. Rich and vibrant and just a little bit vowelly.

Step 1: Use it in the kitchen

Soften brown sugar. Brown sugar. It tastes so good. But it's not always the easiest sugar to work with, because it gets clumpy and lumpy after a while. With some aluminum foil, however, you can soften brown sugar in the oven! Wrap your brick of brown sugar in aluminum foil, then pop it into the oven for five minutes at 300F. Soon you will have softened brown sugar for all of your sugary needs. (You could always just do this in the microwave, but maybe you don't have any microwave- or oven-safe flatware. Or a microwave.)

Pie crust protector. Some aluminum foil folded over the crust of a pie will keep the crust from browning and blackening and eventually falling off before the rest of the pie has cooked sufficiently. This use: useful but not unusual. Its usefulness far outweighs its ordinariness.

Pressure cooker lifter. Placing and lifting bowls into and out of a pressure cooker can be dangerous. Hot food, hot bowls, and slippery surfaces make for a situation fraught with danger. Aluminum foil makes an excellent lifting apparatus to safely and securely raise the precious contents of your pressure cooker without scalding your hands, arms, counter, floor, or curious dog. Just use a piece of aluminum foil that's the size of your bowl plus about eight additional inches. You're making a sling of sorts to lift out the bowl with your newly-made aluminum handles. Fold the foil lengthwise two or three times for strength, then place your bowl into the cooker with your shiny improvised lifter. Fold the handles down during cooking, then use them to lift out your hot bit of deliciousness.

DIY cake pans. Oh no! It's your nephew's birthday and you were supposed to get him a cake shaped like Darth Vader wearing bunny ears. But you forgot because you were busy mayonnaising your hair. Don't panic! You can make yourself an awesome custom cake pan using aluminum foil and some creativity. Just use some aluminum foil inside another baking pan to create the outline of whatever cake you're trying to make. (This is great for county fairs when you want to make something in the shape of the county to woo city council into preferring your home-baked tribute to local government.)

Oven cleaner. You can protect your oven from thrills and spills by placing a few sections of aluminum foil beneath something that might bubble, bubble, toil, and trouble all over the floor of your oven. Don't foil the actual floor of the oven, as that could cause a build-up of heat to warp the bottom of your expensive appliance. Instead, lay some foil over the rack just beneath whatever it is that might erupt and create a mess. Instead of scrubbing until your elbows run out of grease, you can just ball up the soiled foil and recycle it. BONUS OVEN TIP: to protect your heating elements from the harsh chemicals in store-bought oven cleaner, put some aluminum foil over them before spraying down the interior of your oven. [EDIT] This may cause a potentially explosive chemical reaction, but your heating elements will appreciate your thoughtfulness while the house burns down.

Scrubber. I'm a big fan of cast iron frying pans. They're great, but clean up is sometimes a disaster. Using salt and paper towels works most of the time, but egg and rice (and the combination thereof after fried rice) tend to grip the pan like limpets. With a little bit of crumpled aluminum foil, I can scrub off tough messes. This works anywhere you might find yourself scrubbing unusually hard like post-casserole Pyrex, forgot-about-the-pasta-and-all-the-water-boiled-off pots, and caramel that's Maillarded to the point of crumbly blackness.

Campsite cooking utensils. The next time you're camping, you can lug around an entire kitchen set, or you can take a light roll of aluminum foil and fashion your own utensils and pans. You can make a frying pan using a forked stick with aluminum foil stretched over the crook. You can easily make plates and bowls, wrap veggies and meat, or even fold a spoon, fork, or spork out of aluminum foil.

Reheat crispy things. I enjoy the occasional pizza delivered to my door from a company whose name comes from a popular dotted-tile game. But I can't always finish the pizza in one sitting, and I need to reheat the delicious cheesiness. I'll microwave when I'm in a rush, but if I want ideal flavor I go to the oven with some aluminum foil. I set the slice directly on the foil and fold an edge over the crust to protect it from the heat. Bake at 350F for five or so minutes (or broil in high for two) and bam!: fresh-ish pizza. This method has the added advantage of instilling false olfactory hope in a roommate.

Henckelsy?

Were you wearing your tin foil hat when you wrote that!?
wilgubeast (author) in reply to discowhaleFeb 5, 2013. 10:38 AM
Sometimes you just need a brand-specific adjective where none exists. I considered Ginsuish, Wüsthoffian, and Shunlike, but Henckelsy just has a nice ring to it. (I am still partial to Wüsthoffian, actually, but that's just 'cause I enjoy umlauts.)
discowhale in reply to wilgubeastFeb 5, 2013. 1:28 PM
LOL. I love Ginsuish, but now I get Henkelsy, I just didn't 'see' it last night. I'm umlaut challenged myself, so I shy away from them.

Use it with electronics:

A small piece of foil will complete the circuit if you have ill-fitting batteries. I've also used it successfully as a short-hand fix for iPods where one earphone no longer works - a small strip inside the jack to complete a weakened or broken circuit (Replace with a new cable ASAP!)

If you have rechargeable batteries, it can also be useful to fix batteries registering as "bad" in the charger - bridge between the bad battery and a good one in the charger (pos to pos and neg to neg) This will allow enough trickle charge from the "good" battery to build up the bad one until the charger can take over.
taleya in reply to taleyaSep 28, 2012. 11:49 PM
oh, and we've also used it short-term as a blocker. One of our windows used to draw in a lot of direct radiant heat during summer, so we put tinfoil across the inside of it to reflect it back out.

Have since covered it with a shade :)

This is great!
Just want to add an additional way to KEEP your iron from getting gunky when doing patches or other iron on stuff. Cut a stack of aluminum foil sheets the shape of your iron sole plate + about an inch all around. When you're going to do something messy, set the iron on a sheet and fold it up around the lip of the edge. Transfers heat just fine. And if it gets gunky, toss in the recycling when you're through.

I would really like to know why using your scissors on the foil would make them sharper..

Wouldn't any use of the sharp edge, decrease it's overall sharpness?
Arano in reply to Marinus84Mar 14, 2012. 7:19 PM
It is because of the way things are cut with scissors; you also improve sharpness if you cut sandpaper. You only scratch the surface of the outer edges of the scissors. It is similar to the way rats sharpen their teeth.
gralan in reply to Marinus84May 24, 2011. 3:06 PM
I was surprised to find out how wonderful the scissors in our house cut after learning this trick about 3 years ago.

I'm not sure why it works, but it does.

I must admit that anything that causes the blades to separate though defeats the purpose of scissors, so I've never used but 2-3 layers myself (a small piece folded over). I generally don't "cut" to sharpen more than 3 times.

good luck!
mr_eand1der in reply to Marinus84May 15, 2011. 8:09 AM
Well, thinking about it, what most people call the process of sharpening is actually honing the edge (or drawing the burr, or some such).  The edges are already defined on a good pair of scissors, so the process of cutting through the foil will be drawing a hard clean edge (of several layers of foil) across both blades in a direction perpendicular to the cutting edge.  It's _roughly_ analogous to the way sharpening steel is used on a knife edge.

I wouldn't recommend it for expensive shears (say $100+ cloth shears), but for that $5 pair of plastic-handled paper shears that have seen better days?  Totally!

Just be careful not to force the issue; a few layers sounds about right, but anything that requires too much force will distort the swivel and throw off the tension and gap between the blades.
ElectroFrank in reply to Marinus84May 15, 2011. 7:25 AM
All ordinary aluminium is covered in thin layer of aluminium oxide because the surface oxidises as soon as it comes in contact with air. Aluminium oxide is so hard that it is used in abrasive papers and grinding wheels.

I would guess that cutting the foil might grind the cutting surfaces, but perhaps it just cleans and polishes them really well. Anyone got a better theory ?

im using aluminum cans as armor plating fo my braser 2.0
shellyrae says: Jan 16, 2012. 10:26 PM
Sorry if this is a repeat...didn't want to go through 113 replies.... I use foil as an armature for my sculptures. I bend wire (even an old hanger works) to simulate the image (say, a human body) then I bend, wrap, crinkle the foil around the wire armature. This helps decrease the amount of clay needing to be used and gives a nice "white canvas" to your sculptural masterpiece!
SIRJAMES09 says: Jan 9, 2012. 3:47 PM
back in the day when I would go camping at remote locals, I would always take AT LEAST 2 ROLLS of aluminum foil.

The foil helps to block the dampness & cold from coming up thru your sleeping bag & also your tent...never mind the fact that it is just about THE best thing to cook with over an open fire.

The uses for Aluminum foil are only limited by one's imagination.
When I was finished on each camping trip, whatever I packed in ALWAYS got packed out.

I'm not sure which I love more - the fantastic 'ibles I spend far too much time browsing/absorbing, or the utterly fascinating discourse that follows most of them..I JUST LOVE THIS COMMUNITY OF FUNKY, UBER-SMART, AND HILARIOUSLY FUNNY FOLKS!!!

Or, you can seal your hardened brown sugar in an air-tight container with a slice of bread. It'll soften right up. Works well for cookies that have gotten hard too ;)
wilgubeast (author) in reply to AmyLuthienDec 12, 2011. 11:49 AM
I actually use this technique as it's far less work than foil. But if foil's all you've got...
AmyLuthien in reply to wilgubeastDec 12, 2011. 2:18 PM
True!
AlexandraBristow says: May 16, 2011. 2:22 PM
I prefer foil to saran wrap and have routinely only bought foil to cover my left overs. However, my boyfriend, who is a chef, recently told me that saran wrap is better because foil alters the taste of food. Is this true?
kedwa30 in reply to AlexandraBristowSep 14, 2011. 9:01 PM
Because Saran Wrap allows oxygen to pass through whereas foil does not, foil is actually superior for preventing freezer burn. But if the food is only stored for a short while this may not be worth consideration. Wrapping a hobo dinner requires the foil to be creased tightly to keep the steam in. When foil is used to cover a dish, say, in the fridge, there is not as tight a seal as saran wrap. So basically foil is superior for long term freezing and for hobo dinners.
Use of fluoridated water with aluminum cookware tends to also increase the amount of aluminum consumed; not just acidic foods. The non-stick coating in pans contains aluminum. Aluminum is one suspected cause to dementia and definitely is not good to eat.
tpatten-scheinost in reply to AlexandraBristowJul 9, 2011. 2:02 PM
I do not think I have ever tasted an alteration of taste in food wrapped in foil. It is far preferable in the freezer for prtection also, so it wins in my book. Just sayin', lol
lorenrad in reply to AlexandraBristowJun 2, 2011. 6:54 AM
If the foil does not touch the food, you should have no problem.
wilgubeast (author) in reply to AlexandraBristowMay 16, 2011. 2:31 PM
Yes, especially foods with a lot of acid. The acid interacts with the aluminum and can leave a metallic taste.
AlexandraBristow in reply to wilgubeastMay 16, 2011. 3:12 PM
Thanks! I guess I will have to start buying saran. Yuck! So that being said, would it affect the taste of polished silver while eating food?
wilgubeast (author) in reply to AlexandraBristowMay 16, 2011. 3:37 PM
Aluminum shouldn't change the taste of anything besides acidic foods. The silver polishing trick will just take off the oxidized layers of silver from your silverware; it should have no effect on taste whatsoever.
jakebaldwin in reply to wilgubeastMay 16, 2011. 7:53 PM
What about burritos? I swear, every time I bite into my school-issued formerly foil-wrapped burrito, I taste foil. It's quite blegh tasting.
wilgubeast (author) in reply to jakebaldwinMay 17, 2011. 11:16 AM
I bet that those burritos stay wrapped in foil for days. If it's anything like the school-issued food in a not-to-be-named school district in California, the taste of foil is the best flavor you'll get from a school meal. (Generally school lunches, especially burritos, are prepared well in advance. Then they're reheated inside the foil. Sometimes more than once. Yummy.)
AlexandraBristow in reply to wilgubeastMay 16, 2011. 4:33 PM
Thank you! You = Genius!
kedwa30 says: Sep 14, 2011. 8:51 PM
Metallic fabric is sold specifically for people who want to create a faraday cage around their bed because it has been shown that EM radiation can disrupt sleep. Grounded AF strips hung around the bed are a cost effective alternative to reduce the disturbing EMR. Light is electromagnetic radiation. Some people's pineal gland is sensitive to non-visible EMR as well.

When one shapes it into a dish on the head, then it makes sense it would reflect the signal from the inside of the dish only to concentrate it at a point inside the wearers head. Signals from behind the head will bounce off harmlessly. When grounded, the AF should absorb the EMR rather than reflect it. A potential solution would be to shape a hat that did not have the concentration properties of a satelite dish. Or create an aluminum face shield. Silver Surfer anyone?

After reading about using scissors to cut up the aluminum soft drink cans( on instructables, of course ) I decided I'd give it a try. I had a pair of formerly nice scissors that I had gotten at an estate sale. The scissors were already dull to the point of not even cutting paper so I figured cutting the aluminum couldn't do much more damage. I was completely surprised to find that after cutting the aluminum the scissors became sharp enough to cut paper smoothly again. Not sure why but it worked.
raugustine1 says: Sep 11, 2011. 3:07 PM
Aluminum foil makes for a great last second Faraday cage. If you want to test this, wrap your cell phone in foil and try to call it. Your phone will receive no signal and all your electronics will be safe from EMP.

Seems like Aluminum is just as useful as duct tape. So many uses.
shizumadrive says: May 15, 2011. 10:14 AM
Most amazing thing I've used it for was to remove rust from old pocket knives. With just water ,using aluminum foil like steel wool and a little pressure you can remove rust without leaving any scratch marks on the knife.

I've removed rust from knives that have been rusty for at least 50 years that I never thought would look good again.
lorenrad in reply to shizumadriveJun 2, 2011. 6:50 AM
That sounds like a thermite type of chemical reaction going on. The aluminum has a greater affinity for oxygen, so it steals the oxygen from the rust, leaving pure iron behind. Mixing iron oxide and aluminum powder together will produce an intensely hot reaction when ignited.

Try this next time :) You just need a small dc current, really any ac-dc converter would do, for example a pc power supply.
