10 Places People Forget to Clean Around the House
Even the tidiest homes have their secrets—dusty corners, grimy crevices, and hidden build-up in spots that don’t make the regular cleaning list. These are the sneaky spots that tend to be missed, not because anyone’s careless, but because they’re simply out of sight and out of mind.
Over time, though, those overlooked places can accumulate dirt, bacteria, and odours that quietly affect the overall cleanliness of your home. Whether it’s the top of the kitchen cupboards or the back of the radiator, knowing what to watch for is half the battle.
In this guide, we’ll uncover 10 of the most common forgotten areas—along with simple ways to deal with them—so you can keep your home truly clean from top to bottom.
1. Behind the Radiators
It’s one of the most common sneaky spots people never think to clean. Unless you’re moving furniture or doing DIY, you’re unlikely to peek back there. But over time, the gap between the wall and radiator becomes a magnet for dust, pet hair, and debris.
This hidden build-up can affect air quality and even the efficiency of your heating. To clean it properly, use a radiator brush or the narrow nozzle on your vacuum cleaner. A blast of compressed air can help dislodge stubborn fluff. It’s a quick job, but one that makes a big difference.
2. Top of Kitchen Cabinets
The tops of your kitchen cabinets are out of sight—and usually out of mind. But this forgotten zone collects a thick layer of grease mixed with dust, creating a sticky film that’s surprisingly unpleasant when left too long.
It’s one of those places you may skip because you can’t see it without climbing up. Use a step stool and a degreasing spray or warm soapy water with a microfibre cloth. For easy future cleaning, some people line the tops with newspaper or greaseproof paper—just swap it out every few months.
3. Under Large Appliances
Out of reach and out of view, the space beneath your fridge, cooker, or washing machine is a dust trap—and often one of the dirtiest places to clean. Crumbs, pet hair, spilt liquids, and even dropped utensils can all accumulate here unnoticed.
If the appliance is moveable, slide it out carefully and sweep or vacuum the area thoroughly. Follow up with a mop or cloth and a bit of disinfectant to deal with any sticky residue. If it’s built-in or too heavy to move easily, use a long, flat duster or vacuum attachment to reach underneath.
4. Inside Window Tracks
Window tracks are easy to overlook, especially if the glass itself looks clean. But over time, these narrow channels collect dust, dead insects, mould, and grime—making them one of the more unpleasant places to clean.
To tackle them, start by vacuuming out loose dirt using a nozzle attachment. Then spray the tracks with a mix of white vinegar and warm water or your preferred cleaning solution. Use a small brush or an old toothbrush to scrub into the corners, then wipe clean with a cloth or paper towel. A cotton bud works well for tight spots.
5. Light Switches and Plug Sockets
These are high-touch areas used every day, yet they rarely make it onto weekly cleaning checklists. Light switches and plug sockets can harbour germs, fingerprints, and dust—especially around the edges.
Use a slightly damp cloth with a mild disinfectant to wipe them down. For more stubborn grime, a cotton bud lightly sprayed with cleaner helps get into crevices. Always turn off the power if you’re doing anything more than a quick wipe.
6. Skirting Boards Behind Furniture
Skirting boards might get a regular wipe—unless they’re hidden behind sofas, beds, or wardrobes. These out-of-sight spots collect dust, cobwebs, and scuffs over time, making them one of the more commonly forgotten areas.
Shift the furniture if you can, then vacuum along the skirting using the brush attachment. Follow up with a damp cloth and your usual cleaning solution. A quick dust and wipe can instantly lift the look of a room.
7. Shower Curtain or Screen Seal
Bathrooms get a lot of attention, but the rubber seal at the bottom of a shower screen—or the folds of a fabric curtain—are classic places you may overlook. These damp, hidden spots are prime territory for mould, mildew, and soap scum.
For screens, scrub the seal with a mix of baking soda and white vinegar to lift grime and kill bacteria without damaging the surface. For curtains, check the label—many fabric ones can go straight into the washing machine. If not, soak it in warm water with a bit of detergent, then rinse and hang it out to dry fully. Always follow the advice on the label.
8. Remote Controls and Game Controllers
Used daily but rarely cleaned, remotes and controllers are some of the most touched—and least sanitised—items in the home. They easily pick up grease, food residue, and germs, especially if snacks are involved.
To clean them properly, remove the batteries first. Use a slightly damp cloth with a small amount of disinfectant to wipe the surfaces. For the gaps around buttons, a cotton bud or a soft bristle brush works well. It’s a quick job that helps cut down on bacteria in an often-missed spot.
9. Under the Bed and Behind Headboards
These spaces are out of sight, which makes them magnets for dust, fluff, and the odd lost sock. Under the bed is one of the most common forgotten areas, especially in rooms with limited space.
Use a long vacuum attachment or extendable duster to reach underneath. If your bed has drawers, pull them out and clean around the frames. Behind the headboard, dust and cobwebs can quietly gather—so give that area a proper clean while you're at it. A quick clean here can make a surprising difference to air quality in the bedroom.
10. Inside Rubbish and Recycling Bins
Even with liners, bins get messy. Leaks, food residue, and condensation can build up inside, creating bad smells and bacteria. It’s one of those places to clean that often gets overlooked simply because it feels like a job that can wait—until it can’t.
To clean them properly, take the bins outside and rinse them with hot water. Scrub the inside with bleach, disinfectant, or a mixture of baking soda and washing-up liquid, paying attention to the lid and any corners. Let them dry fully before replacing the liner. Do this every other week to keep odours and germs under control.
Bonus: The Washing Machine Drawer and Seal
It might sound odd, but the very appliance that cleans your clothes often hides a grimy secret. The detergent drawer and rubber door seal of your washing machine are prime spots for mould, old soap residue, and even black slime.
Slide the drawer out fully and soak it in hot, soapy water or a vinegar solution. Use a toothbrush to scrub inside the compartment. For the seal, wipe thoroughly with a cloth and disinfectant, lifting the fold to reach hidden gunk. You’ll be surprised (and possibly horrified) by what builds up here. While you’re at it, don’t forget to give the dishwasher a proper clean too—check the filter, spray arms, and door seals for food deposits and grime.
Conclusion
It’s easy to focus on the obvious when you’re cleaning—floors, worktops, sinks. But it’s the overlooked spots that often hold the most hidden grime. From the top of your kitchen cabinets to the rubber seal on your washing machine, these are the sneaky spots that really benefit from a more thorough approach.
Adding just one or two of these to your weekly cleaning or monthly checklist can make a noticeable difference in how fresh and hygienic your home feels. With the right cleaning supplies, a few smart cleaning tips, and a simple way to clean each spot, you’ll stay on top of the dirt and dust without much extra effort.
