Northern New Jersey homes go through a lot each year. Months with the windows shut, salt and slush tracked in all winter, then pollen that settles on every sill in spring. A seasonal deep clean catches what regular cleanings don't reach.
In the kitchen, start with the inside of the refrigerator and oven, then empty and wipe out cabinets and drawers. These are the jobs that only need doing a few times a year, but make a real difference when they're done.
Through the rest of the house, focus on the details: baseboards along every wall, window frames and sills, interior window glass, and blinds dusted slat by slat. Pollen and winter dust collect in exactly these places.
Bathrooms get a full scrub of tile and grout lines, and bedrooms get fresh linens and a thorough dusting of every surface, including tops of dressers and headboards that rarely get touched.
Finally, take the chance to organize. A deep clean is the perfect time to clear a pantry shelf or a closet that's gotten out of hand, so the house stays easier to keep clean the rest of the year.
