One thing I truly love about waking up each morning is the opportunity to learn something new. If that something happens to be a new use for an item I already own quite a bit of, even better. I’ve always loved mayonnaise. It’s delicious on sandwiches, in egg salad, and even alone. But now I'm discovering that my beloved mayo has other super-secret powers. Read on and discover the many things your extra jars of mayo can do!

1. Get the gunk off

Whether your particular brand of gunk is adhesive, plant sap, gum residue, or other yucky gummies, mayo can help you remove it without scratching or otherwise harming the underlying surface.

  •  Just smear mayonnaise over the gunk, let it sit for 5-10 minutes, then use a blunt knife (a butter knife works well) to gently scrape away the gunk.

2. Give yourself a home spa treatment

Whether your problem is frizzy hair, weak nails, or dry skin, mayonnaise can give you the many benefits of spa treatments without the expense.

Note: If any of the mayo in your stockpile contains olive oil, choose those jars for these treatments.

  • For skin: Smooth mayo on areas of dry skin (as you would with lotion). Let the mayo work itself in for 5-10 minutes, then wash with warm water.
  • For hair: Spoon out some mayo and work it into your hair from the scalp out (like you would with a deep conditioner). Let it sit for 15-20 minutes, then wash out with warm water.
  • For nails: Spoon out some mayo into a shallow dish. Submerge all 10 fingers for 5-10 minutes (up to the cuticles) then remove and gently wash with warm water. If you have a hangnail, be sure to give it a bit of extra mayo – this will help it heal faster.

3. Brighten up ivory and silver

In time, items made of genuine ivory tend to yellow. This is due to exposure to the elements, frequent handling and the natural process of aging. Whether the ivory in question are the keys on your family's piano or a precious ivory statue from a trip, mayonnaise can restore it to its original white glory. In the same way, silver tends to tarnish with time and age, and mayo can rescue it and make it shine again.

  • This treatment is very easy—just smooth on a small amount of mayo over the yellowed surface. Wait about 5 minutes, then wipe off with a soft cloth (microfiber works great here).

4. Eradicate head lice

Sometimes it’s hard to believe that head lice is still an issue in today's modernized society, but the little buggers simply refuse to die out. Luckily, mayo can hasten that process. Many doctors now prescribe mayo in lieu of other, more toxic, commercial solutions.

  • Work a generous helping of mayonnaise into the scalp and hair, then cover the whole head with a shower cap. Let the mayo sit in the hair overnight. In the morning, rinse hair and scalp with warm water.

5. Ease painful sunburn and other burns

Summer is nearly here, and sunburn is as much a part of summer as beaches, watermelon and flip-flops. Luckily, mayonnaise can ease sunburn just as effectively as more expensive solutions. This treatment works equally well for any issue with burned skin.

  • Smooth on some mayo over the painful, sunburned areas. Wait 5-10 minutes, then rinse off with cool water. Repeat as needed.

6. Clean hard-to-reach areas and difficult stains

From light switches to floor cracks, mayo can help loosen and pick up dirt, dust, grime and other matter. This trick also works with stained wood, paint stains, and other hard-to-remove stains.

  • Smooth on just a bit of mayo, wait a minute or two, then wipe away with a soft cloth. For especially narrow crevices, a toothbrush can help to remove dirt and matter.

7. Pinch hit as an egg substitute

When you’re baking something with eggs, it’s never good to discover mid-recipe that you are out of eggs! Luckily, mayo contains eggs and can serve as a workable substitute.

  • Add three tablespoons of mayonnaise for every egg the recipe calls for. You can also add an extra dab of mayo for extra moistness.
