Portland winters are more wet than white. Here is how to keep mud, leaf litter and damp grit out of the house through the city's three wettest months and the occasional freeze.
Ask a Portland household what winter does to their floors and the answer is rarely snow. It is wet: dog paws, rain boots, umbrellas dripping by the door and a fine paste of grit and leaf crumbs that ends up in every entry. November, December and January are the three wettest months of the year at the airport, and December's normal high is only about 47 degrees, so very little dries quickly.
This guide is about getting through that stretch with a home that still feels clean. It covers the door, the floors, leaves and yard debris, the few days of ice and snow, and how to set a cleaning plan for the season.
Portland International Airport's 1991 to 2020 normals show 5.45 inches of precipitation in November, 5.77 in December and 5.03 in January, out of a yearly total of 36.92 inches. Measurable rain falls on about 157 days a year. December's normal daily high is 46.9 degrees.
Freezing weather is a smaller part of the picture. The airport averages about 32 nights a year at or below freezing and a normal of 4.2 inches of snow, mostly in December, January and February. When ice does come, it brings its own mess: de-icer, sand and gravel tracked onto floors that are used to plain mud.
Most winter dirt enters through one or two doors. Treat them as a system rather than a single mat:
Leaf drop runs into the rainy season, and wet leaves stick to everything. The City of Portland asks residents to sweep leaves from sidewalks and streets because leaves left in place clog storm drains and flood intersections. Sweeping the walk and steps also cuts down what gets carried inside, since wet leaf fragments break into crumbs that settle along baseboards and in floor seams.
Portland's curbside compost cart takes leaves and other yard waste along with food scraps and food-soiled paper. Wet leaves are heavy, and the City warns that a 60-gallon cart can reach its 135-pound limit before it is full. Fill it partway across several pickups rather than packing it in one go.
Wet grit is abrasive. On hardwood, vacuum entries and hallways more often than in summer, then damp mop with very little water. Tile and vinyl near back doors can take a fuller mop. Pay attention to the bottom two inches of every wall, where mop water and tracked grit collect, and to the corners behind doors.
Older homes need extra care. About 27 percent of Portland homes were built in 1939 or earlier, and their original floors often have thin finish that wet grit wears through. Their single pane windows also run with condensation on cold mornings. Wipe sills and the bottom rail of each sash, and keep window tracks clear so water drains instead of pooling. Dark spots that keep coming back point to a moisture problem that needs a contractor, not more cleaning.
On the few icy days a year, the mess changes. Rock salt and de-icer leave a white film on floors and can dull wood finish; wipe them up with a damp cloth and plain water, then dry the floor. Sand and fine gravel scratch, so sweep or vacuum them before mopping. Keep a separate mat by the door for those days, and shake it outside rather than vacuuming the grit into the house.
These events are usually short in Portland, so there is no need to change a cleaning plan for them. On an icy morning it is reasonable to move a visit by a day.
Households with dogs, kids or a garden often move to weekly Recurring House Cleans from the first heavy rains through the end of the wet season, then step back to bi-weekly once things dry. Smaller homes without pets usually stay on bi-weekly all winter. Each recurring visit dusts reachable baseboards and blind slats, which is where wet season grime settles.
When the rain eases, a One-Time Deep Clean clears the winter's buildup: baseboards washed by hand, window tracks scrubbed, blinds wet-wiped, vents and fixtures wiped in place. The recurring cleaning guide and the seasonal calendar cover the rest of the year.
