We all know we need to periodically clean our pillows – at least three times a year! – but do we know when to stop cleaning and just get a new one? It might sound a little wasteful, but you actually do need to replace your pillows on a regular basis for your own health and cleanliness. Luckily, not only do you not have to do it as often as you might fear, but there’s a simple test you can do to find out for sure if it’s necessary. Here to demonstrate is Melissa of Clean My Space, and she shows just how easy it is. Give it a try!
