Inversions in January, mud in April, smoke in August, first snow in November. This calendar places each cleaning job where it helps most in a Salt Lake Valley home.
Spring cleaning advice was not written for a place where the worst air of the year can come in January. So this calendar follows what actually goes on in the valley, using NOAA's normals for the airport along with Utah DEQ's notes on air quality.
Move a job forward or back as the weather requires. The order matters more than the exact week, and bench homes in places like Draper or SunCrest may see snow and wind a little differently from the valley floor.
Normal annual precipitation at the airport is 15.52 inches, with April the wettest month at 2.16 and July the driest at 0.49. Snow totals 51.9 inches: 12.7 in January, 12.1 in December, 10.7 in February, 7.0 in November and 5.9 in March. There are about 112 nights at or below freezing and about 62 days at 90 degrees or hotter, with a normal July high of 94.
Salt Lake City notes air quality problems in both seasons: winter inversions and summer ozone driven by heat and bright sunshine.
This is the heart of the snow season, at 35.5 inches. Keep boot trays and absorbent mats at every door, and wash them often. Utah DEQ says inversions trap cold air and fine particles, with a typical winter averaging 18 days of PM2.5 above the federal standard. Keep windows shut then, and dust with a damp cloth, as fine particles settle on shelves and screens.
Wipe registers and vents, and change HVAC filters on the maker's schedule. On a clear, mild day, air the house out for a while. It is also a good stretch for closets and storage rooms, since there is little reason to be outside.
March still brings a normal 5.9 inches of snow, and April is the wettest month. Mud comes next, so keep the entry mats out. Once the inversions end, this is the best moment in the year for a One-Time Deep Clean: the windows can stay up for drying, and a whole winter of settled dust is ready to come off fans, blinds and baseboards.
Check the basement and window wells after the melt. Standing water or a damp wall is a job for a contractor, since TotalCare Cleaning does not repair water damage.
AAFA's 2026 report says that for Salt Lake City, Provo and Ogden, grass pollen lasted longer and weed pollen started earlier, lasted longer and peaked higher. The city placed 13th of 100 metro areas. Keep windows closed on high count days, wash curtains and bedding more often, and rinse off pets.
The city begins blending in more groundwater when mountain stream runoff drops, and it describes that water as harder. If you have been putting off treating shower glass, this is the time to get on top of it.
July is the driest month at 0.49 inches, with a normal high of 94 degrees. Summer ozone adds to the air problems, and DEQ describes dust from the shrinking Great Salt Lake as a major concern, with the city downwind of the dry lakebed. Wipe sills and tracks more often and close up on windy days.
DEQ also warns that wildfire smoke can get inside homes, even from fires in other states. Once a smoky stretch clears, dust and wipe flat surfaces, wash soft furnishings and swap your HVAC filter. If you still notice a smell, a few extra days of airing usually helps.
Weed pollen can run long, so keep your habits going until the weather turns. Wash windows, clean tracks and sills, and wipe fan blades before the home closes up for winter. November brings a normal 7.0 inches of snow, so have boot trays and mats ready. Before the holidays, degrease cabinet fronts and soak stovetop grates.
Salt Lake City residents can book their remaining Call 2 Haul pickups in this window, as garbage service includes one for bulk waste and one for green waste each year. Leftover glass goes to monthly collection or a drop-off site rather than the blue can.
