October Cleaning Checklist: 15 Things to Do This Month

October Checklist sign in fall colors.

October is when everybody moves back inside. The windows close. The jackets come out. The kitchen gets busier. And the patio furniture sits outside, waiting for someone to notice it's almost November.

The holidays are close, but not that close. You don't need to deep-clean the whole house before Halloween. A few jobs this month will make November and December a lot easier, keep the house safe now that the heat's back on and get you ready for guests before they ring the doorbell.

Here are the 15 that matter. No marathon required.

1. Clean the Entryway for Fall

The entryway takes a beating in October: jackets, boots, backpacks, umbrellas and the soccer cleats nobody put away. So:

  • Put away the summer stuff, like flip-flops, beach bags and sunscreen.
  • Shake out or wash the doormat, then sweep and mop the floor.
  • Give every jacket, shoe and bag a hook, a bin or a shelf.

You don't need a custom mudroom with twelve matching baskets. You just need the front door to open all the way.

And if you're decorating the porch for Halloween, use battery-operated LED candles in your jack-o'-lanterns. Real candles plus kids in costumes plus dry leaves is not a good combination.

2. Dust the Places You've Been Ignoring

Hand cleaning the exterior of a lampshade.

This isn't your usual quick dusting. This is the stuff you've been walking past since spring:

  • Ceiling fans
  • Light fixtures
  • Lampshades
  • Tops of tall furniture
  • Window sills
  • Baseboards
  • Air vents and registers
  • Door frames

Turn off ceiling fans and lights first, and let bulbs cool. For fan blades, slide an old pillowcase over each one and pull it off. The dust stays inside the pillowcase instead of raining down on you. Work from high to low, and do two rooms at a time, not the whole house.

3. Vacuum Under the Furniture

Move the couch, the chairs and anything else you can safely slide, and vacuum underneath. Do the family room first, since you'll be living in it all winter. You'll probably find dust bunnies, pet hair, three pens, a dog toy and the remote you replaced in July.

4. Deep-Clean the Living Room

Your living room is about to get a lot more use, so give it more than a quick tidy:

  • Vacuum the upholstery, including under the cushions.
  • Dust tables and lamps with a microfiber cloth, and wipe TV screens and electronics with a dry one. No spray.
  • Wipe down remotes, light switches and door handles.
  • Clear off the coffee table and side tables.

The goal is a room that's comfortable to live in, not one staged for a magazine shoot.

5. Wash Blankets and Throws

Pull out the cozy blankets and wash them before winter, following the care labels. Keep your favorites where everyone can grab them. Then donate or toss the worn-out extras. No one gets a prize for owning eleven throw blankets.

6. Give the Oven Some Attention

Clean the oven now, not the night before Thanksgiving. Scrape out burned-on crumbs, clean the inside following the manufacturer's directions and wipe down the stovetop, knobs and oven door.

If you use the self-cleaning cycle, take out the racks unless your manual says they can stay in. Open a window, and keep pet birds out of the house. The fumes can kill them. Never use commercial oven cleaner in a self-cleaning oven.

7. Clean the Refrigerator and Freezer

Holiday groceries are coming, so make room now:

  • Toss anything expired or spoiled, and any leftovers older than 3 to 4 days.
  • Check the condiments in the door. Some of them are older than your car.
  • Wipe up spills and wipe down the shelves.
  • Clear out the freezer.

That unidentified frozen package from another geological era is taking up valuable real estate.

8. Declutter the Pantry Before Holiday Shopping

Take stock of your baking supplies, canned goods and spices before you shop for the holidays. Toss anything expired, group like with like and write a list of what you need. This isn't about a pretty pantry. It's about not buying a fifth container of cinnamon because the first four were hiding behind the pasta.

9. Clean the Guest Bathroom

Even if you don't have guests coming yet, you will. Clean the:

  • Sink and faucet
  • Counter
  • Mirror
  • Toilet
  • Tub or shower
  • Floor
  • Trash can

Then restock it with fresh towels, toilet paper, soap and a spare toothbrush. Toss the nearly empty bottles.

One rule: never mix cleaning products, especially bleach with ammonia or vinegar. The fumes are toxic.

10. Check the Linen Closet

Don't reorganize the whole thing. Just pull out the threadbare towels, the sheets that don't fit any bed you own and the mismatched pillowcases nobody uses. Group the sheets by size, and keep guest towels where you can reach them. This is a linen closet, not a lifestyle transformation.

11. Check Smoke and Carbon Monoxide Alarms

This is the most important job on the list. Heaters, fireplaces, candles and holiday cooking all start up this time of year.

  • Test every smoke and carbon monoxide alarm by pressing the test button.
  • Replace standard batteries once a year. Daylight saving time ends the first Sunday in November, and that's an easy reminder.
  • Replace smoke alarms every 10 years, and CO alarms by the date printed on them, usually 7 to 10 years.
  • Make sure you have CO alarms on every level of the house and outside each sleeping area.

12. Prepare the Heating System

Check your heat before the first cold night, not during it:

  • Replace the furnace filter. Most disposable filters need replacing every 1 to 3 months. Don't try to clean them.
  • Move furniture and rugs off the vents and registers, and vacuum the dust out of them. Otherwise that dust is the first thing your furnace blows around the house.
  • Schedule a furnace tune-up now, before the repair people are booked solid.
  • If you have a wood fireplace, get the chimney inspected and swept once a year.
  • Keep space heaters at least 3 feet from anything that can burn, and never leave them running when you leave the room or go to bed.

13. Inspect Doors and Windows for Drafts

On a windy day, hold your hand near the edges of your exterior doors and windows. If you feel cold air, you've found a draft. Replace worn weatherstripping, add a door sweep and caulk small gaps. Make sure every window closes and locks. Small fixes make the house warmer and cut your heating bill.

14. Put Away Summer Outdoor Gear (and Clean the Gutters)

Clean patio furniture, cushions, toys and the grill before you store them. Otherwise you'll meet mildew in the spring. Toss anything broken instead of granting it winter accommodations in the garage.

  • Store propane tanks outside, upright and away from the house. Never keep them in the garage, a shed or the basement.
  • Store gasoline only in an approved container, away from heat, and add fuel stabilizer to the lawn mower or run it dry.
  • Clean the gutters once most of the leaves have fallen. Clogged gutters mean overflowing water and ice dams this winter. Use a sturdy ladder, and have someone hold it. Better yet, hire someone.

15. Clear One Clutter Hotspot Before the Holidays

Not a whole room. Not the whole house. Just one spot:

  • Entryway
  • Kitchen counter
  • Dining table
  • Guest room closet
  • Coat closet
  • Pantry
  • Living room surfaces

Set a timer for 15 minutes. Toss the trash, put things back where they belong and bag up anything you clearly don't want for donation. Skip anything that needs a big decision. The goal is a clear surface, not an existential crisis over a gravy boat.
