4. Remove dark-wood furniture scratches with leftover coffee.
Dip a cotton ball or Q-tip in leftover coffee or directly into recently used grounds and dab directly onto scratches. Be sure to immediately wipe away any liquid that has dripped onto non-scratched wood to prevent damage. Dark, strong coffee works best.

All you need is two egg yolks, vinegar, salt, and a little bit of oil to make your own mayo without the additives! Check out The Kitchn for a great, easy recipe.
6. Clean a dirty grill with leftover onion.

7. Kill weeds with pickle juice.
The amount of salt and vinegar in pickle juice is perfect for killing weeds!
8. Plant sprouted potatoes.
Instead of throwing away sprouted potatoes, carefully cut around the sprout or “eyes” so that you have a piece of potato that is about the size of a chicken egg. Leave the pieces out for a couple of days, then dig a hole in your garden about four inches deep and plant the potato sprout-side up. Don’t water the potato until the sprout breaks through the soil.
Note: You can also grow vegetables from sprouted garlic and other leftover vegetable scraps. Check out 7 Vegetables You Should Never Pay For for more details.

10. Trap fruit flies with stale red wine.
Pour about an inch of stale red wine into a glass or container and cover it with plastic wrap. Poke a few holes in it. Flies can get in, but can’t get out.
You can also create a paper cone (making sure it forms a small whole at the bottom) and secure it onto a jar or container with tape.

Add this compound butter to fish and steak dishes for pure deliciousness.
12. Create bread crumbs with stale bread.
Place leftover bread in an oven heated to 250 degrees for about 10 minutes or until the bread has lost most of its moisture. Then, run the bread through a food processor or use a box grater.
13. Freshen air with citrus peels.
Boil citrus peels in water for a few minutes then decrease heat to low and let the peels simmer for as long as you’d like. Add more water if necessary.
14. Bake bread with sour milk.
Sour milk may not be great for drinking, but it works perfectly well in bread recipes. You won’t be able to taste the difference!
