Dirt resides almost undetectably on paint and wallpaper, in floor grooves, and among the “clean” pots and pans in cabinets — until suddenly it’s not so undetectable anymore. (You could have sworn you picked Studio White, not Gutter-Water Gray, for the kitchen walls.) Here’s how to make short work of the buildup.

Walls

Allen Rathey, president of HousekeepingChannel.com, swears by this routine (first see Before You Clean Your Walls).

Step 1: Prepare your tools: Fill a bucket with plain lukewarm water to clean your sponge as you work. In a spray bottle, mix about 20 ounces of water and a tablespoon or so of Woolite or dishwashing liquid.
Step 2: Working in sections and wiping off drips as you go, spritz on the solution and let it sit for five minutes. “Use less product, but give it time to work so there’s less work for you,” says Rathey.
Step 3: Wipe each section with a clean, damp (not wet) sponge. Rinse and wring out the sponge periodically so you don’t spread dirty water back onto the clean wall.

Wood Floors

Experts agree: Wood floors and water don’t mix, and refinishing is strictly for pros, so dust and spot-clean with vigilance.

Step 1: The golden rule: Vacuum or dry-mop wood floors at least once a week (some experts say every other day). The longer dust and dirt sit on the wax or finish, the more dulling and scratching will occur.
Step 2: When spills or scuffs appear on polyurethaned floors, use a slightly damp mop or sponge to lift them. If they’re stubborn, use a bit of the cleaner the floor manufacturer recommends to break them down.
Step 3: When the floor begins to look scratched or dull, call in the professionals to do one of two things: scuff-sand and recoat the finish, or sand and completely refinish the floor.

Cabinets

Sadly, closed doors don’t always deter dust and dirt. Open your cabinets and wash them out.

Step 1: Empty cabinets of all pots, pans, and utensils and give the interiors a thorough dusting with a microfiber or electrostatic cloth. Press it into corners, under ridges, and along door edges.
Step 2: With a solution of dish soap and warm water and a damp (not wet) sponge, clean the bottoms, tops, and walls. Rinse the sponge in clean water as you go. Dry with a clean towel or rag as you work.
Step 3: Consider an idea from How Clean Is Your House?’s Aggie MacKenzie: Store muffin tins, woks, and other rarely used things in plastic bags so you won’t have to rinse dust off the next time you use them.
