Cleaning is one of those tasks everyone thinks they know how to do—until you realise just how many misconceptions surround it. At Merci Cleaning, we’ve seen it all: over-scrubbed surfaces, ruined appliances, wasted products, and frustrated homeowners. Much of this comes down to common cleaning myths that simply won’t go away.
Let’s set the record straight. Here are five persistent cleaning myths you should stop believing today—and what to do instead.
Myth 1: Bleach cleans everything – one of the most persistent cleaning myths
The truth: Bleach is a powerful disinfectant, not a cleaner. It kills bacteria and viruses, but it doesn’t remove dirt or grime.
Using bleach on dirty surfaces without cleaning them first is like spraying perfume on sweaty gym clothes—it might mask the smell, but the problem is still there. Surfaces should first be washed with soap and water or a proper multi-surface cleaner to remove dirt, then disinfected if needed.
Better approach: Use a mild detergent or an all-purpose cleaner for the initial clean. Disinfect only when necessary (like in kitchens, bathrooms, or during flu season), and always follow the manufacturer’s instructions for dilution and dwell time.
Myth 2: Vinegar is a universal cleaning miracle
The truth: While vinegar is great for many tasks—like removing limescale or cleaning windows—it’s not a cure-all. In fact, vinegar can damage certain materials, especially natural stone like marble or granite, as its acidity breaks down the surface.
Also, it’s a common misconception that vinegar disinfects as effectively as commercial solutions. It doesn’t kill all viruses and bacteria, and shouldn’t be your go-to for sanitising food prep areas.
Better approach: Use vinegar sparingly and only on safe surfaces such as glass, chrome, or tiles. For disinfecting, opt for products that are EPA-registered or proven to eliminate 99.9% of germs.
Myth 3: More cleaning product equals better results – among the most common cleaning myths
The truth: It’s easy to think that using extra product will give your floors a better shine or your counters a deeper clean. In reality, using too much can leave sticky residues that attract even more dirt—and may damage surfaces or irritate skin.
Overuse is also a waste of money and can lead to the buildup of harmful fumes, especially in enclosed spaces.
Better approach: Always read and follow the label instructions. Most products are formulated to work at specific ratios. For example, with concentrated floor cleaners, a small capful goes a long way when diluted properly.

Myth 4: You only need to clean when things look dirty
The truth: Waiting until surfaces look grimy means waiting too long. Dust, allergens, bacteria, and mould spores are often invisible to the eye but can significantly affect your health—especially for children, the elderly, or those with respiratory conditions.
High-touch areas like light switches, door handles, remote controls, and phones can become breeding grounds for germs long before they show visible dirt.
Better approach: Develop a regular cleaning routine based on usage, not appearance. For example, disinfect high-touch points weekly, vacuum floors at least twice a week, and deep clean bathrooms and kitchens every 1–2 weeks.
Myth 5: Professional cleaning isn’t worth the cost – in top 5 of the most spread cleaning myths
The truth: Many homeowners view professional cleaning as a luxury. However, it’s actually an investment—especially when you consider the time, effort, and equipment needed for a deep clean. Professionals have the training, tools, and experience to reach places you may miss and handle materials you might accidentally damage.
Professional cleaning is also particularly valuable for:
- End-of-tenancy cleans (to secure your deposit)
- Post-renovation mess
- Seasonal deep cleans
- Allergy-proofing your home
Better approach: Even one or two professional cleans per year can maintain your home’s condition, extend the life of carpets and upholstery, and improve indoor air quality. Think of it as preventive care for your home.
