Experts recommend replacing an open box of baking soda in your refrigerator about once a month. When you do replace the box, don't throw away the old baking soda. Instead, sprinkle it in the shower; wipe it up with a sponge, and your shower will be sparkling clean. You can also get your outdoor grill clean by using a mix of baking soda and water to scrub off the crusty, grimy mess. And if you have old books, sprinkle some between the pages and place it in a plastic bag; wait a few weeks, and you'll have a fresh, mildew-free tome.

When you pump gas and smell it, it's not just obnoxious -- it could also be toxic. The fumes you smell are likely benzene and toluene, which can lead to health problems. When pumping gas, the proper way to fill up is to insert the nozzle into the tank, and use the "hold-open latch," which pumps gas continuously without needing to hold the nozzle. Stand a few feet away to avoid the fumes, and be sure to not top off the tank, which can release additional fumes into the atmosphere.

Around 26 percent of all fruits and vegetables grown in the United States never make it to store shelves because they look ugly or irregular. Even though the produce is perfectly fine to eat, stores think consumers want only perfect apples, tomatoes and other perishables. The Ugly Fruit and Veg Campaign (endfoodwaste.org) is working hard to change the perception that irregular is bad -- instead, it's great. To help, Instagram pics of funny-looking produce using #uglyreallyisbeautiful and buy irregular stock at your supermarket.
