Do you remember to clean these spaces in your home? Most people, even people who consider themselves to be very tidy, forget to clean these parts of their homes.
Bathroom - Your shower head. It's good to take your shower heads off every now and then and really clean them and remove the minerals. One good way to do this is by soaking it in vinegar and using some sort of brush to scrub it clean. Remember to let the water run through it afterward before showering.
Kitchen - The top of your refrigerator. We tend to forget to clean what we can't see. So when you're dusting your kitchen, don't forget the top of your fridge!
Living Room - Underneath your couch cushions. Unless we are missing a remote or drop something inside the couch, most of us don't even see underneath the couch cushions. Take out the vacuum and get underneath there once in a while. You'd be surprised what's hiding underneath them!
Bedroom - The drawer pulls on your dresser. We touch them every single day while getting inside our dresser or nightstand, so they are covered in bacteria. But when is the last time you sanitized them?
