When it comes to household maintenance, there’s a lot that needs to be done — from the floors to the ceiling fans and everything in between, including tough spots, like toilets and nooks and crannies behind the couch. And while you might know a thing or two about the best vacuums or the best multi-purpose sprays to get the job done, the people who really know how to tackle a home in the most safe and efficient way are the ones who do it every day: professional cleaners. And according to the experts, some of the most common household cleaning mistakes — like sweeping up crumbs before clearing countertops — not only waste your time, but others can even be potentially hazardous, like mixing incompatible cleaning agents. Correcting even the most innocent of the bunch could add precious minutes back to your day, and we’re all about efficiency here.To help you get the job done the right way, we asked professional cleaners to dish on the top mistakes homeowners make and how to correct them. Using too much of a cleaning product“Many people think that using more cleaning solutions or sprays will lead to cleaner surfaces resulting in cleaner areas,” says Ryan Knoll, owner of Tidy Casa in Phoenix, Arizona. “Overusing cleaning sprays, solutions or bottled products can leave behind heavy residues on surfaces that may attract debris and dirt or cause streaks that you never want.” Mixing cleaning products”People often think that if one product works, mixing it with another one will make it even better,” says Carolyn Forté, executive director of the Good Housekeeping Institute Home Care & Cleaning Lab. But certain duos that can pose a serious threat to your health and the environment when mixed together. Take bleach and vinegar, for example. “Together, they produce chlorine gas, which even at low levels, can cause coughing, breathing problems and burning, watery eyes,” says Forté.PSA:Using the wrong cleaner for the wrong surfaceYou know how most carpet cleaning products come with a disclaimer that suggests you try a test spot before tackling a larger area? That’s because some cleaning products aren’t compatible with certain fabrics or surfaces and can cause irreparable damage. For example, when cleaning your laptop screen, you should never use a glass cleaner, says Forté. Another example? Though vinegar may sound like a gentle and all-natural cleaner, you should never use it to clean natural stone surfaces, as the acid can damage the stone, she says.Cleaning out of orderA lot of people take out the vacuum first, but you should really start at the top, says Knoll. Clean the curtains, the fan in the living room, the pictures, the TV, the entertainment center… everything else goes before the floor. Why? While you’re cleaning these spots, dirt will inevitably fall, littering your freshly vacuumed or mopped hardwood floors or carpeting, says Knoll. In the end, you’ll have to repeat a task you thought you’d already completed — a complete waste of time. FotoDuets//Getty ImagesNeglecting high-touch spotsHigh-touch spots are areas in the home that get touched by hands constantly throughout the day: door handles, light switches, remote controls, gaming controls, refrigerator door handles, microwaves, etc. These small areas may seem insignificant, so they often go overlooked, but can harbor a significant amount of dirt and bacteria because of how much they get used, says Knoll, who recommends cleaning these areas at least weekly. “Wipe them down with a solution of soap water, or disinfecting product or wipe,” he says. TOP-TESTED CLEANING PRODUCTSSteaming hardwood floorsEven though some steam mop manufacturers claim it’s safe to clean hardwood with steam, Forté does not recommend these appliances for use on wood (sealed, waxed or unfinished) and laminate floors — even on the lowest steam settings. Since most wood floors are not completely sealed, steam can penetrate the finish and warp the wood. When cleaning wood floors, we recommend a good old-fashioned wet mop instead. sefa ozel//Getty ImagesIgnoring nooks and cranniesWhen you ignore hard-to-reach spots — like the space behind the toilet — the dirt builds and may even get embedded into floors or woodwork, making it much more difficult to clean, says Joseph Passalacqua, CEO and owner at Maid Sailors Cleaning Service in New York. Buying into all of the cleaning hacks out thereYou could easily find yourself scrolling TikTok’s #CleanTok for hours on end, but our pros say you shouldn’t believe everything you see on the internet. Take laundry stripping, for example. While it is technically safe for sturdy white, off-white or colorfast fabrics, Forté says the process of laundry stripping can be time-consuming and inconvenient — and that there are other, better ways to avoid build-up in your fabrics. Using dirty cleaning toolsAlways clean your tools immediately after using and replace them as needed. Dirty cloths, mops, and full vacuum cleaner bags won’t effectively remove dirt and debris, Forté, who says you’ll end up working extra hard with minimal results to show for it.
