You Shouldn't Be Using Q-Tips in Your Ears. Here's How to Clean Your Ears the Right Way

Earwax is just a fact of life. We need it to protect the inner ear and lubricate the ear canal, though honestly, excess earwax can be annoying. Not only can it make it difficult to hear what's going on around you, but no one wants to find earwax on their earbuds.

And you definitely don't want to get it wrong if you value your hearing. Many health care professionals adv

Shark Steam Pickup 3-in-1 Hard Floor Cleaner Review: A Do-It-All Cleaning Gadget

To me, mopping is like filing my taxes or changing my oil. A necessary evil that I dread, a task that I procrastinate until I have no other choice. Luckily, I've been testing steam mops, which means I stopped mopping entirely in order to assess how well each model cleans. The floors of my 250-square-foot high-traffic kitchen have been … how do I put this … really gross.
