When it comes to cleaning, most of us focus on the obvious areas—countertops, floors, and frequently used surfaces. But what about the hidden spaces that accumulate dust, grime, and even mold over time? Deep cleaning these overlooked areas can improve air quality, eliminate hidden allergens, and keep your home feeling fresh. Here are some essential tips for tackling forgotten spaces in your home.

Under Sinks and Inside Cabinets

Over time, leaks, spills, and general humidity can cause mold and grime to build up under kitchen and bathroom sinks.

  • How to Clean: Remove everything from the cabinet, wipe down the surfaces with a disinfectant, and check for leaks or mold growth.
  • Extra Tip: Place a moisture-absorbing product or liner to prevent future buildup.

Behind and Under Furniture

Couches, dressers, and bookshelves tend to collect dust, pet hair, and lost items when left unchecked.

  • How to Clean: Move furniture periodically and vacuum or mop behind and underneath. Use a microfiber cloth to wipe down walls and baseboards.
  • Extra Tip: Attach an old sock to a yardstick or use a flexible duster for hard-to-reach spots.

Inside Closets and Storage Spaces

Closets often become cluttered with dust and forgotten items. The lack of airflow can lead to stale odors and even mold.

  • How to Clean: Empty the closet, wipe down shelves, and vacuum or mop the floor. Donate or discard items you no longer use.
  • Extra Tip: Use lavender sachets or baking soda to keep closets smelling fresh.

HVAC Vents and Filters

Your heating and cooling system collects dust and debris that can circulate throughout your home if left unchecked.

  • How to Clean: Remove vent covers and vacuum inside ducts. Wash vent covers with warm, soapy water. Replace air filters every 1-3 months for optimal air quality.
  • Extra Tip: Consider scheduling a professional duct cleaning service with A. Borrelli if you notice excessive dust buildup.

Light Fixtures and Ceiling Fans

Ceiling fans and light fixtures are magnets for dust, especially in high-traffic areas.

  • How to Clean: Use a microfiber cloth or a duster to remove dust and cobwebs. For light fixtures, remove and wash covers with warm soapy water.
  • Extra Tip: Use a pillowcase to clean ceiling fan blades without spreading dust.

Behind and Under Appliances

Kitchen appliances like the refrigerator, stove, and dishwasher can harbor crumbs, grease, and dust.

  • How to Clean: Unplug and carefully move the appliances to sweep and mop underneath. Wipe down the sides and back with a degreaser.
  • Extra Tip: Check refrigerator coils for dust buildup, as this can reduce efficiency and increase energy usage.

Final Thoughts

Deep cleaning these often-overlooked spaces can make a significant difference in your home’s cleanliness and air quality. Set a schedule to tackle one or two areas at a time, and your home will stay fresh and healthy year-round.l
