Why Spring Cleaning Is Different in Ontario
Ontario winters are hard on homes in ways that southern climates simply aren't. Road salt tracked in from November through March penetrates entry flooring, baseboards, and carpets — the residue is hygroscopic (it attracts moisture) and continues damaging surfaces after the salt itself is no longer visible. Furnaces running continuously from October through April distribute 5–6 months of accumulated dust through forced-air vents. Freeze-thaw cycles cause window condensation that leaves mineral deposits and potentially mold in sill tracks. Basement humidity swings from the ultra-dry winter (when forced-air heating removes moisture) to the humid spring (when Ontario's spring rains drive relative humidity up quickly) create conditions for mold establishment in basement spaces. Effective spring cleaning in Ontario addresses these specific seasonal effects — not just the generic "dust and vacuum" routine that works in milder climates.
Entry and Mudroom
- Scrub entryway tile or hardwood with a pH-neutral cleaner to dissolve salt residue — do not use vinegar on salt-damaged surfaces without rinsing thoroughly, as the acid can react with the salt compounds
- Clean baseboards in the entry area — salt spray accumulates on the lower 6 inches of wall surfaces and baseboards throughout winter
- Wash and disinfect all door mats (machine wash if possible) or replace if they've absorbed a winter's worth of salt and grime
- Wipe down closet shelves and shoe storage areas — salt residue off boots migrates into storage spaces
- Check weather stripping on all exterior doors and replace if cracked or compressed
Kitchen
- Clean inside the oven — winter cooking (roasting, baking, casseroles) accumulates more grease than summer cooking
- Defrost and clean inside the refrigerator — pull the fridge from the wall and vacuum the condenser coils (lower back of the appliance) for efficiency
- Replace the range hood grease filter — most should be replaced or deep-cleaned every 3–6 months
- Clean inside all kitchen cabinets — crumbs, spills, and condensation from winter humidity accumulate on shelves
- Descale the kettle, coffee maker, and dishwasher with white vinegar or a commercial descaler — Ontario's hard water deposits minerals in heating elements over winter
- Wipe down the inside of the dishwasher including the spray arms and filter basket
Bathrooms
- Deep-scrub shower grout — winter's reduced ventilation (windows closed) accelerates mold establishment; scrub and re-seal grout lines (see our shower grout guide)
- Clean showerhead — run vinegar through the showerhead to dissolve mineral deposits from Ontario's hard water
- Check under sinks for leaks or moisture damage that developed over winter
- Clean exhaust fans — vacuum the cover and wipe the interior; compromised winter ventilation is often due to dusty exhaust fans
- Descale faucets and fixture bases — white vinegar applied with a cloth and left for 15 minutes dissolves winter mineral buildup
Windows and Window Areas
- Clean window tracks — freeze-thaw condensation deposits grime in tracks over winter; use a toothbrush and compressed air before wiping
- Inspect window seals for fogging between panes (failed seal) — this develops over winter and should be addressed before summer humidity
- Wash interior windows — winter condensation leaves mineral deposits on the glass; microfibre cloth with a 50/50 water-vinegar solution
- Check window sills for mold — paint bubbling or dark discolouration at the sill indicates moisture penetration that needs attention before summer
HVAC and Ventilation
- Replace furnace filter — after 5–6 months of continuous operation, a clogged filter reduces efficiency and circulates dust throughout the home
- Vacuum all supply and return vents — winter heating circulates dust through the duct system and deposits it on vent covers
- Schedule furnace maintenance if it hasn't been serviced in the past year
- Turn on and test air conditioning before the first heat wave — spring is the right time, not during the first hot day
- Check bathroom exhaust fans — replace if they're more than 10 years old; compromised ventilation contributes to mold issues year-round
Basement
- Check for moisture — spring rains in Ontario quickly raise basement humidity; look for efflorescence (white mineral deposits on concrete walls), musty smell, or visible moisture on walls
- Run a dehumidifier starting in April — maintain basement relative humidity below 60% to prevent mold establishment
- Clean the sump pump pit and test the pump before spring rains peak
- Vacuum baseboards and the perimeter of the basement floor — dust accumulates at floor level over winter
- Inspect stored items for moisture damage
What to DIY vs. Hire Out
The tasks above break into two categories: routine cleaning (most of the checklist) that any homeowner can handle with time and the right products, and deep cleaning that benefits significantly from professional equipment and experience.
Best candidates for professional cleaning:
- Inside oven, fridge, and full kitchen cabinet cleaning — time-intensive and tedious
- Shower grout scrubbing, especially in large walk-in showers
- Full-home deep clean to reset the baseline after winter — professionals complete in 3–5 hours what takes DIY all weekend
