Even if you clean your house regularly, there are probably a few spots that you forgot about. Of course, when life gets busy, it’s hard to remember to keep up with the less obvious items. But, especially now, keeping things clean is important to living a happy and healthy life. Here is a list of things in your home that you probably never clean, but you should ASAP.

40. Remote Controls

At the end of a long day, many of us like to relax by watching TV. But do you ever think about how many things your hands have touched before you sat down on the couch? Your remote control ends up carrying all of those germs from your hands, as well as anyone else in the house who is using it. According to the Times of India, a remote control is 20 times more dirty than a toilet. Next time you’re cleaning, remember to use disinfectant wipes or spray on your remote control. Also remember to wash your hands after using the remote before you eat or touch your face.

Unless you have a smart home with voice activated lights, chances are that you touch light switches every single day. But how often do you clean them? According to Simmons College in Boston, a light switch has the same amount of germs as a trash can. And a hotel light switch has 112 colonies of bacteria per square centimeter. Yikes! Always remember to clean off your light switches with either disinfectant wipe or spray.

38. Coffee Machine

Many of us make coffee every day. Some even leave the coffee grounds or pod in the machine overnight, and don’t bother to pick up the filter until the next morning. Unfortunately, leaving anything moist in a dark place is a recipe for mold to form. And over time, your coffee machine can also become clogged due to hard water buildup. Remember to periodically clean your machine by running water and vinegar through it without the coffee. Depending on how dirty your machine is, you may need to do this a few times before it’s completely clean.

37. Trash Cans

Since we line our trash cans with plastic bags, most people assume that we never have to clean them. In reality, trash cans are filled with germs, especially in the kitchen where we throw away food containers, egg shells, and more. According to Spoon University, it’s common for trash cans to contain Salmonella, E. Coli, and Listeria. Don’t forget your outside trash cans, either. The next time you have a warm and sunny day, take the time to clean your trash and recycling bins with some dish soap or bleach and water from the hose.

36. Dishwasher

Most people assume that a dishwasher never needs to be cleaned, because it’s basically self-cleaning every time you run a load of dishes. In reality, those bits of food that fall off of your plates need to go somewhere, and it’s usually left in the machine. You can run a cycle using good old fashioned vinegar to clean your dishwasher. There are also dishwasher cleaning tablets sold at the store that you can use as well. If you’d like to know more, Good Housekeeping has an entire guide on the type of cleaning you should be doing on a daily, weekly, and monthly basis to your dishwasher.

According to the Cleveland Clinic, dirty pillows can even make you sick. So be sure to clean them or replace your bed pillow every one to two years.

It’s possible to buy washing machine cleaner from the store, but you can also run a load of plain water and vinegar or bleach to make sure that the inside of the machine is clean.

We brush our hair every day, and yet most of us forget to clean hairbrushes. Over time, they can build up with residue left over from our hair products, as well as the natural oils from our scalp. Plastic hair brushes and combs can be put in the dishwasher for an easy clean. If your brush is made of horsehair and has a wooden handle, you shouldn’t soak the entire brush in water, because it could ruin the wood. Just take a small amount of shampoo and clean the bristles. Let it dry with a towel. Do this once a month, and it should keep your hairbrushes fresh and clean.

Luckily, there are a lot of ways to clean a keyboard. You can use a wipe, q-tips, spray, or even slime to get in-between those little nooks and crannies of the keys.

Also consider flipping your mattress, which will help prevent it from getting indented from your body weight.
