Keep flowers alive
The simple carbohydrates in sugar not only provide nutrients to humans and animals, but to plants as well. Add about 3 teaspoons of sugar and two tablespoons of white vinegar to a vase filled with water. The sugar will help the flowers stay strong and perky, while the vinegar will kill bacteria and keep bugs away from your vase.
Clean and remove odor from coffee grinders and more
Sugar absorbs nasty odors and soaks up moisture that can cause mold. To clean coffee grinders, pour about a quarter cup of sugar into the grinder and let it grind for a few minutes, then wash it out. Your next cup of coffee will taste noticeably fresher. This trick is also great for old thermoses or tupperware. Put about a teaspoon of sugar in the thermos or container and then close tightly (you don’t want any critters coming after the sugar). Rinse out before use. Any stale or unpleasant odors will be gone by your next use.
