Professional cleaners know the right way to clean efficiently and effectively, using smart techniques to get the job done without wasting time or damaging surfaces. While many people take a DIY approach to house cleaning, common mistakes can actually make your home dirtier, spread germs, or even cause damage.
If you want to clean like a pro, avoid these 10 things a professional cleaner would never do when cleaning your home.
1. Using the Same Cloth or Sponge for Every Surface
Reusing the same cloth for wiping kitchen counters, dusting furniture, and cleaning bathroom sinks may seem convenient, but it spreads bacteria, grime, and germs from one area to another. Cross-contamination is one of the biggest cleaning mistakes, especially when moving from bathrooms to kitchens.
Professional cleaners use different microfiber cloths for different areas—color-coding them for kitchen, bathroom, and living areas to prevent cross-contamination. Always wash reusable cloths after each cleaning session, and replace sponges frequently to avoid bacteria buildup.
2. Spraying Cleaner Directly on Surfaces
Spraying cleaning solutions directly onto furniture, mirrors, or electronics can cause streaks, leave residue, and even damage delicate surfaces. Over time, excessive moisture can seep into wood or electronics, leading to warping, discoloration, or malfunction.
Always spray the cleaner onto a microfiber cloth first, then wipe the surface. This ensures even distribution and prevents excess liquid from damaging your furniture or appliances.
3. Using Too Much Cleaning Product
Many people assume that more cleaning solution = better cleaning, but professional cleaners know that using too much can do more harm than good. Excess product often leaves behind sticky residue, attracting dust and grime faster. This means you’ll have to clean again sooner than necessary.
Follow the recommended amount on the product label. If cleaning a heavily soiled area, let the cleaner sit for a few minutes before wiping, rather than overloading the surface with excess product.
4. Forgetting to Dust Before Vacuuming
Vacuuming first might seem logical, but it’s actually the wrong order. When you dust after vacuuming, particles from shelves, furniture, and decor settle back onto your freshly cleaned floors, meaning you’ll have to vacuum again.
Always dust first, then vacuum. Start with high surfaces like shelves and ceiling fans, then work your way down to furniture and baseboards before vacuuming the floors. This prevents dust from resettling onto clean surfaces.
5. Scrubbing Carpet Stains Instead of Blotting
When a spill happens, your first instinct might be to scrub the stain away, but that actually pushes the stain deeper into the carpet fibers, making it harder to remove. Aggressive scrubbing can also fray carpet fibers, leaving an obvious worn-out patch.
Always blot the stain with a clean cloth, working from the outside in to prevent spreading. Use a gentle stain remover, let it sit, then blot again until the stain lifts. For stubborn stains, a steam cleaner can help lift debris without damaging the carpet.
6. Ignoring High-Touch Areas
Most people focus on visible dirt, but high-touch areas like doorknobs, light switches, and remote controls are some of the germiest places in the home. These spots often go unnoticed, but professional cleaners never skip them.
Disinfect high-touch surfaces weekly, especially during cold and flu season. Use a disinfecting wipe or spray to quickly sanitize handles, light switches, appliance buttons, and remotes.
7. Using Harsh Chemicals on Every Surface
While strong chemicals like bleach and ammonia are effective for killing germs, they’re not safe for every surface. Overuse can lead to fading, discoloration, and even respiratory irritation from lingering fumes.
Use gentle, pH-balanced cleaners for delicate surfaces like granite, marble, stainless steel, and wood. If a disinfectant is necessary, choose a milder, non-toxic option like hydrogen peroxide or vinegar-based solutions.
8. Forgetting to Clean Cleaning Tools
Dirty cleaning tools just spread dirt around instead of actually cleaning. Sponges, mops, and vacuum filters collect dust, bacteria, and grime, making them less effective over time.
Wash microfiber cloths and mop heads after each use.
Replace sponges every 1–2 weeks.
Empty and clean your vacuum canister or bag regularly to maintain suction power.
Sanitize toilet brushes by soaking them in a disinfecting solution weekly.
9. Overwetting Upholstery While Spot Cleaning
When dealing with a stain on fabric furniture, using too much water or cleaner can soak into the cushions, leading to mildew, odors, and even structural damage.
Use a small amount of fabric cleaner, blot with a dry towel, and allow the area to air dry completely. If deep cleaning is needed, use a steam cleaner or professional upholstery service.
10. Ignoring the Baseboards and Air Vents
Baseboards and air vents often go unnoticed during regular cleaning, but guests and family members will definitely notice the dust buildup. Dirty vents reduce air quality, and dusty baseboards make an otherwise clean room look messy.
Vacuum or wipe down baseboards with a damp microfiber cloth monthly. Use a vacuum attachment or damp cloth to remove dust from air vents to keep your home looking clean and fresh.
