Updated: Nov. 28, 2023
These areas of your home have been neglected for way too long! It’s time to roll up your sleeves and give them each a deep clean.
Inside Dryer and Dryer Vent
Built-up lint inside dryer cabinets causes more than 15,000 fires every year. Lint escapes through tiny gaps around the edges of the dryer drum and falls into the cabinet, especially when the exhaust vent or vent cap is clogged and airflow is restricted. The lint can get ignited by electric heating elements, gas burners or even a spark from the motor, and the flames then travel through the lint-lined exhaust vent. To make sure this doesn’t happen in your house, check the exhaust vent and the inside of the cabinet frequently.
Faucet Aerators
Aerators are found on almost every kitchen and bath faucet, and if water flow slows or becomes uneven, clogs inside the aerator are usually the cause. Fortunately, it’s an easy problem to fix.
Oven
Built-up spills and remnants of old food and liquids inside ovens can cause smoke and smell issues. It’s important to clean up big spills as they happen, and make it a habit to put your oven through its cleaning cycle regularly. But when you’re really trying to make your oven shine, you might need to go further. Learn how to clean between the glass panels of your oven door here.
Bath Fan Grill
Household dust, moisture and humidity combine to cake bathroom exhaust fans with debris. Often located on the ceiling, you may not notice it’s even dirty. Luckily, bath fan grills are easy to clean. Grab the edge of the cover and pull down. Squeeze the springs to release them from the slots and remove the cover. Learn about the 7 ways you might be cleaning your bathroom wrong.

Clean Window Weep Holes or Invite Rainwater Into Your House
Many sliding windows and vinyl replacement windows have weep holes on the exterior bottom of the frame. These holes are designed to drain away rainwater that can collect in the frame’s bottom channel. Weep holes can get plugged with bugs and debris, and if that happens, water could fill up the channel and spill over into your house.
To see if your weep system is working, simply pour a glass of water into the track or spray the outside of the window with a garden hose. If you don’t see a steady stream of clean water exiting the weep hole, poke a wire hanger into the hole, or spray it out with compressed air, and wet it down again. If the little flapper (designed to keep out driving wind) is stuck shut, it can be removed with a putty knife and replaced.
Door Knobs
We all have them, and we all touch them. But when was the last time you cleaned your door knobs? It only takes a few minutes to kill any lingering germs—just be careful not to get any on wood doors or trim, because it could affect the finish. This is the best all-purpose cleaner you can buy.

Light Switches
Just think about how many times a day you use a switch on the lights. And no matter how clean you think your hands are, each time you touch the light switch, you’re spreading germs. Wipe them down regularly with a disinfected spray or cloth.
The Computer Keyboard
In addition to the germs on your hands, your keyboard collects food crumbs, hair and dead skin cells. Every two months, use compressed air to get all the crumbs out.

Phone

Pillows
You don’t need to wash your pillows every week like you do your sheets, but every three months or so, throw them in the washing machine on a gentle cycle with hot water to remove dead skin cells and sweat. And when drying, add a couple of clean tennis balls to help speed up drying and keep the pillow guts from clumping.
Remote
Just like your phone, you touch the remote with dirty hands and spread those germs and dead skin cells around. So wipe it down once a week with a microfiber cloth and a little rubbing alcohol, or a disinfectant wipe. Before you wipe it down, be sure you’re not mixing these 20 common cleaning products.
Your Toothbrush
To make sure your toothbrush is as germ-free as possible, keep it away from other toothbrushes and in a bathroom cabinet or cupboard so it’s safe from airborne bacteria.
