Most businesses think their workplace is cleaner than it actually is. Not because they don't care — but because some of the most common cleaning mistakes are easy to make and hard to spot until they've already caused a problem.
Here are the most frequent cleaning mistakes we see in commercial spaces across Newfoundland, and what to do about each one.
This is the most widespread mistake of all. Routine cleaning — vacuuming, mopping, wiping surfaces, emptying bins — is essential, but it only maintains a surface level of cleanliness. It doesn't address what accumulates over time in carpets, grout, air vents, behind furniture, and inside appliances.
Without periodic deep cleaning, buildup compounds quietly in the background. By the time it becomes visible or noticeable, it's already been affecting air quality, floor condition, and hygiene for months.
The fix: Schedule a professional deep clean every one to three months depending on your traffic and industry, in addition to your regular routine cleaning.
Floors and bins get cleaned because they're visible. Door handles, light switches, shared keyboards, lift buttons, and kitchen appliance handles get touched dozens of times a day by multiple people — but they're frequently missed in routine cleaning because they don't look dirty.
These surfaces are the primary route through which illness spreads through a workplace. Neglecting them is one of the fastest ways to increase employee sick days.
The fix: Make high-touch surface sanitization an explicit, non-negotiable part of your daily cleaning checklist — not an afterthought.
Not all cleaning products are suitable for all surfaces. Using an abrasive cleaner on a polished floor, a bleach-based product on a surface that reacts badly to it, or a general-purpose spray on a screen or electronic device can cause permanent damage — and sometimes create chemical hazards in the process.
This mistake is particularly common when staff handle cleaning informally without proper training or guidance.
The fix: Ensure whoever is cleaning your space — in-house or outsourced — knows which products are appropriate for which surfaces and follows manufacturer guidelines.
Dwell time is the amount of time a cleaning or disinfecting product needs to remain wet on a surface in order to be effective. Most disinfectants require between 30 seconds and 2 minutes of contact time to actually kill pathogens — but in practice, many people spray and immediately wipe, rendering the product far less effective than intended.
The fix: Train cleaning staff to apply products and allow the correct dwell time before wiping. Check the product label for the recommended contact time.
Office kitchens are among the most bacteria-laden spaces in any commercial building — consistently ranking higher than restrooms in studies of workplace hygiene. Shared appliances, sink areas, and food preparation surfaces are touched constantly and cleaned inconsistently.
Many businesses clean the kitchen visually — wiping down the counter and rinsing the sink — without addressing inside the microwave, behind the kettle, fridge door seals, or the underside of appliance handles.
The fix: Include a detailed kitchen cleaning checklist in your routine cleaning schedule and add a monthly deep sanitization of all appliances and surfaces.
A mop that hasn't been properly cleaned between uses, a vacuum with a full or dirty filter, or a cloth used across multiple surfaces without being changed — all of these spread bacteria rather than removing it. Dirty cleaning equipment is one of the most counterproductive mistakes a business can make.
The fix: Establish clear protocols for cleaning and replacing equipment regularly. Professional cleaning companies use colour-coded cloths and replace mop heads routinely to prevent cross-contamination.
In high-traffic businesses, restrooms can deteriorate significantly between scheduled cleaning visits. A restroom that was clean at 8am may be in poor condition by midday — and a client or visitor who uses it at 2pm will judge your entire business accordingly.
The fix: For client-facing businesses or those with significant foot traffic, restrooms should be checked and maintained multiple times throughout the day — not just cleaned once and left.
In Newfoundland, winter brings salt, slush, and moisture into every commercial building from November through April. Many businesses keep the same cleaning schedule year-round, then wonder why their floors are deteriorating or their entrance areas always look grimy.
The fix: Increase floor cleaning frequency during winter months, add entrance matting, and schedule a post-winter deep clean in spring to address salt damage and buildup.
The cheapest cleaning quote is rarely the best value. Low-cost providers often cut corners on time, products, training, and equipment — and the results show up quickly in the condition of your workplace.
The fix: When evaluating cleaning companies, ask about their training, the products they use, their insurance and bonding, and whether they have experience in your specific industry. Price matters, but it shouldn't be the only consideration.
Without a documented checklist, cleaning becomes inconsistent. Tasks get skipped, standards drift, and there's no reliable way to identify what's being missed until a problem becomes obvious.
The fix: Insist on a written cleaning checklist for your facility and establish a simple quality control process — even a monthly walkthrough against the checklist is enough to catch issues before they compound.
At Spurview Cleaners we build detailed, documented cleaning plans for every client — so nothing gets missed, standards stay consistent, and your workplace stays genuinely clean rather than just looking clean on the surface.
