It’s not all that surprising mayonnaise is such an incredibly versatile condiment when you consider what it’s made of: olive oil, egg yolk, lemon and salt. (Here’s a quick recipe for homemade mayo.) Each of those ingredients can enhance the moistness and richness of about any food, and can also do wonders around the house.
Psst… Here’s a step-by-step tutorial on how to make the most of your mayo.

Bake a moist chocolate cake
The oil makes any cake more tender, a little extra egg yolk enriches any baked good and the acid in lemon has a way of making the flavor or chocolate pop! Put ’em all together, and you’ve got mayo, which is the secret to this top-rated, super-moist Mayonnaise Chocolate Cake. And you won’t even have to crack an egg!

Make the best grilled cheese ever
When it comes to creating the crispest, tangiest crust on your grilled cheese sandwich, butter is good, but mayo is better.

Unstick your grilled fish
Ninety-nine percent of the time, when I fail at cooking fish on my outdoor grill, it’s because the fish sticks to the grates. How to remedy this? Why, mayo, of course. It adheres so nicely to the fish, plus it adds a slightly acidic richness to the end result. Slather an even layer of mayo all over the fish you’re about to grill, and grill away!

Make bread crumbs stick to fish
Regardless of where you’re cooking your fish, ever notice how hard it is to get bread crumbs to adhere to the surface? The solution is simple: mayonnaise. Slather your fish in a thin layer before bread crumbing for best results.

Keep chicken breast moist
Slathering chicken breasts in mayonnaise before cooking will not only tenderize the chicken (thanks to the acid from the lemon) but will also keep your chicken moist while it cooks. The proof is in our delicious Parmesan Chicken!

Perfect your potatoes
Grilled potatoes are great. But grilled potatoes with mayo are even greater because the mayo helps the potatoes retain a bit of moisture while they grill up crusty on the outside. You can toss the cubed potatoes with mayonnaise and seasonings before you put them in a foil packet.

Remove watermarks from wood
To eliminate watermarks on wood, rub mayo on the mark, let it rest for several hours and wipe. It works because the moisture in the mayo displaces the moisture locked in the wood, effectively unlocking it. And mayo stays moist long enough to do the unlocking (whereas oil would tend to evaporate).

Remove crayon marks
Did a young artist let creativity reign…on your walls? The oils in mayo are perfect for breaking down crayon marks. Simply dab it on, let it sit for a bit and then wipe away.

Wipe away fingerprints on stainless steel
A little mayo on a microfiber cloth does wonders for making fingerprints disappear from your stainless steel appliances.

Get chewing gum out of your hair
We won’t ask how it even happened, but it doesn’t have to be a disaster. Simply rub a bit of mayo onto the affected hair, and it will soften up the gum so you can remove it painlessly (and without scissors). Don’t miss these other gum-be-gone solutions,too.

Polish ivory piano keys
This is a real tip, according to music experts Merriam Music. The bacteria present in mayonnaise helps clean your yellowed ivory piano keys gently. Be sure to buff with a dry cloth after cleaning.

Shine up those houseplants
Treat your houseplants right because not only are they aesthetically pleasing, they improve your air quality (especially these houseplants). A microfiber cloth plus a dab of mayo will have them looking polished in no time.

Soothe your sunburn
The oil and egg yolk in mayonnaise and its soothing texture make it a perfect salve for soothing sunburn.

Condition your hair
Rich in fats and proteins, the egg yolk in mayo is naturally moisturizing as well as nourishing. The oil seals in that moisture. Apply to hair like you would any conditioner, let sit for 20 minutes and then rinse and cleanse with a gentle shampoo.
