3Neglecting your biggest touch points.
GettyFaucets, handles, and door knobs are some of the most-touched areas in your home, which is why they're also the germiest. Take to 'em with a disinfectant wipe daily to keep germs at bay.
4Getting lazy with the coffee pot.

5Spraying furniture with polish.
GettyWhen you spray furniture directly, it creates build-up that's tough to remove and attracts even more dust (womp, womp). To avoid this, spray your cloth with the cleaner, then rub the cloth on dusty surfaces.
6Using the same rag everywhere.
GettyStreaky surfaces? You might be over-using your cleaning cloth and spreading germs while you're at it. Even if your towel doesn't look old, it should be washed after each use since it's used on high-traffic (read: dirtier) areas.

7Using a feather duster. Period.
Westend61//Getty ImagesWe'll give you a thumbs up for dusting, but a thumbs down for using a tool that only spreads dust from one surface to another. Use a microfiber cloth instead, which will grab — and hold onto — particles.
8Not dusting your windows.
GettyBefore washing them, that is. If you forget to tackle the dust on your sills, any window cleaner that drips onto the frame will become a muddy mess of dusty liquid. A vacuum or microfiber cloth will tackle the mess nicely.

9Storing a wet toilet brush.
GettyWell hello, breeding ground for bacteria! Instead of just dropping your wet brush into the holder, set it across the seat so it can drip-dry over the bowl before putting it away for good.
10Forgetting your trash can.
Getty ImagesIf you notice an unpleasant odor in your kitchen, it might be an indicator that you haven't clean your trash can in awhile. Wipe it down once a week with a cleaner containing bleach to keep nasty smells under control.

13Using dish soap for everything.
Getty ImagesWhile this grease-fighting product is powerful, it leaves streaks behind on surfaces that aren't plates and cups. So you should steer clear of using this liquid soap on your car windows and mirrors.
14Pouring in too much fabric softener.
gerenme//Getty ImagesWe get it: You want to sleep on the softest sheets possible. But using more product than is recommended by the manufacturer will have the opposite effect: "Just pouring it in usually adds too much and that can make fabrics stiff and scratchy, or even greasy, and reduce towels' absorbency," says Forte.

15Using dirty sponges.
Danielle Occhiogrosso DalyThese cleaning superheroes won't, in fact, be that helpful if you don't sanitize 'em every few days (and replace them every month). To do this, soak your sponge in water, place it in a microwavable dish, then heat it on high for a minute.

17Using too much laundry detergent.
Good HousekeepingRaise your hand if you've ever poured in a little extra detergent for an extra dirty load of laundry. Well it turns out if you use too much, the cleaner and your stains might not rinse out of clothes. Yikes!
18Keeping toothbrushes in the dark.
David McGlynn//Getty ImagesSure, the medicine cabinet might seem like a safe, germ-free environment, but the lack of light actually makes it a breeding ground for bacteria. Instead, keep your brush out in the light — just make sure you close the lid on the toilet when you flush.

19Overlooking reusable bags.
Getty ImagesEspecially grocery bags, which likely have lingering food bacteria on them. You should treat them like any other fabrics in terms of care, but just turn them inside out before tossing them into the washing machine.
