The 10 Cleaning Spots Ontario Homeowners Miss Most — 2026

10 Cleaning Spots Ontario Homeowners Miss Most

Every Ontario homeowner has blind spots — surfaces and spaces that never make it onto the cleaning rotation because they're not visible, not intuitive, or not part of the cleaning habits passed down from the last generation. Here are the ten most consistently missed.

1. The dishwasher filter: The removable filter at the bottom of the dishwasher tub catches food particles — most people don't know it exists, let alone that it should be cleaned monthly
2. The top of the refrigerator: Accumulates a dense layer of grease and dust that's invisible from standing height but is the first thing guests see when they're tall or enter from a step
3. Refrigerator coils: On the back or underside of the fridge — dust accumulation reduces efficiency and shortens fridge life. Vacuum annually
4. Door frames and tops of doors: Dust settles on the top edge of every interior door and the horizontal door frame surface above
5. Light switch plates and outlet covers: Among the most touched surfaces in the home, cleaned least often
6. Under the kitchen sink: Product residue, drips, and potential early water damage from slow pipe leaks
7. The washing machine drum and seal: The front-load washer rubber door gasket accumulates mildew; the drum itself needs a monthly cleaning cycle
8. Window tracks: Compacted with debris and visible only when you look
9. Bathroom exhaust fan grille: Covered in lint and dust, restricting airflow and promoting bathroom mould
10. The area behind the toilet: Floor behind and around the toilet base — rarely reached with the mop, accumulates the same grime as the rest of the bathroom floor but faster
