How Often Should You REALLY Clean These 10 Overlooked Areas in Your Home?

We all have our go-to cleaning routines — wiping counters, vacuuming floors, and doing the dishes. But what about the spots you don’t think about every week? These overlooked areas can collect dust, grime, and even bacteria over time.

At Night and Day Cleaning, we’ve seen it all and we know just how much of a difference tackling these spots can make. Here’s our list of 10 places that often get skipped, plus how often you should clean them and exactly how to get them done.


1. Inside the Stove

How often: Every 6 months
How to clean: Spray the entire oven interior with oven cleaner, making sure to keep the racks inside so they can soak. Let it sit for 3–4 hours. Start by cleaning the inside of the door, then remove the door for better access — most oven doors slide right off without tools when opened. Continue cleaning the inside of the stove, scrubbing away baked-on residue, then replace the door once it’s spotless.


2. Behind Appliances

How often: Once a year
How to clean: Unplug the appliance for safety. Carefully slide it away from the wall. Use a vacuum with a hose attachment to remove crumbs, dust, and cobwebs from the floor and wall. Wipe down the wall, baseboard, and floor with warm, soapy water, paying attention to any grease or sticky spots. Let everything dry completely before sliding the appliance back into place.


3. Intake Vents

How often: Every quarter
How to clean: Unscrew or unclip the vent covers and remove them. Use a vacuum with a brush attachment to clean both the cover and the inside edges of the vent opening. For a deeper clean, wash the vent covers in warm, soapy water, rinse, and dry before reinstalling.


4. Windowsills

How often: Monthly
How to clean: Use a handheld vacuum or small brush to remove dust, dirt, and debris. Dampen a cloth with warm, soapy water and wipe the sill thoroughly, getting into the corners. If you spot mildew, mix equal parts vinegar and water, apply to the affected area, and wipe clean. Dry completely to prevent future mold growth.


5. Inside the Microwave

How often: Every 2 weeks
How to clean: Fill a microwave-safe bowl with water and a few lemon slices (or 2 tablespoons of vinegar). Microwave for 3–5 minutes until the liquid boils and steam coats the inside. Let it sit for 2 minutes with the door closed. Remove the bowl carefully, then wipe the interior walls, ceiling, and floor with a damp cloth, using the softened food splatters to your advantage.


6. Dishwasher Seal

How often: Every quarter
How to clean: Open the dishwasher and inspect the rubber seal around the door. Dip a soft cloth or old toothbrush in warm, soapy water or white vinegar. Scrub along the grooves and edges of the seal, making sure to remove food particles, soap scum, and mold. Wipe dry with a clean cloth before closing.


7. Vent Under the Fridge

How often: Every 3–4 months
How to clean: Remove the vent cover at the bottom (it usually snaps off or has a couple of screws). Use a vacuum with a long, thin hose to remove dust and pet hair from the coils and surrounding area. This not only keeps things clean but also helps your fridge run more efficiently.


8. Under the Bed

How often: Every 1–2 months
How to clean: Remove any storage bins or items from under the bed. Use a vacuum with an extension wand to reach all the way to the center. For hardwood or tile, use a microfiber mop or dusting tool to collect dust bunnies. Return items after wiping them down so they don’t reintroduce dust.


9. Under the Bathroom Sink

How often: Every 6 months
How to clean: Take out all items from under the sink. Wipe down the cabinet walls and bottom with warm, soapy water. If you notice any mildew or water damage, clean with a vinegar-water mix and let dry completely. Consider adding a shelf liner or mat to protect against future leaks and spills.


10. Baseboards

How often: Every 2–3 months
How to clean: Start by running a dry microfiber cloth or duster along the baseboards to remove loose dust. For stuck-on dirt, dip a sponge or cloth in warm, soapy water and gently scrub. Use a cotton swab or old toothbrush for corners and detailed trim. Dry immediately with a clean cloth to prevent water damage.
