Cleaning vs. Sanitizing vs. Disinfecting: What’s the Real Difference?

Keeping your space safe and healthy takes more than just a quick wipe-down. To truly protect against germs, bacteria, and viruses, it’s important to understand the difference between cleaning, sanitizing, and disinfecting—and how each fits into a complete hygiene routine.

Whether you’re running a commercial kitchen, managing an office, or just trying to keep your facility looking professional, knowing when and how to use the right products is key. Let’s break it down.

What Is Cleaning?

Cleaning refers to the removal of visible dirt, debris, and dust from surfaces. While it doesn’t necessarily kill germs, it reduces their number by physically removing them. This is the first step in any maintenance routine and makes sanitizing or disinfecting more effective.

Common Cleaning Tasks:

• Sweeping floors
• Wiping down countertops
• Dusting furniture
• Washing windows

At Polished Janitorial, we stock high-performance all-purpose cleaners and multi-surface sprays that are ideal for everyday messes.

Tools You’ll Need:

• Microfiber cloths
• Mops
• Buckets
• Spray bottles
• Scrub pads

Pairing these tools with a quality neutral floor cleaner ensures your floors aren’t just visibly clean—they’re ready for the next step.

What Is Sanitizing?

Sanitizing reduces the number of bacteria on surfaces to a safe level, as determined by public health standards. It’s often used in food service environments or child care facilities where germs can spread quickly.

Sanitizing is effective for:

• Food preparation areas
• Cutting boards and kitchen tools
• Shared toys and play surfaces
• Office break rooms

Best Products for the Job:

Our Hypochlorite Sanitizer is a powerful choice for sanitizing sinks, equipment, and other high-use surfaces. It’s widely used in commercial kitchens and restaurants.

Why It’s Important:

Even after cleaning, small traces of bacteria may linger. Sanitizers help kill enough of these microorganisms to prevent the spread of illness, without being as intense as a disinfectant.

What Is Disinfecting?

Disinfecting goes one step further than sanitizing. It involves using chemical agents to destroy bacteria, viruses, and fungi on hard, non-porous surfaces. This is critical in high-risk environments such as hospitals, clinics, and washrooms.

Disinfecting is necessary for:

• Toilet handles and bathroom sinks
• Doorknobs, light switches, and elevator buttons
• Shared electronics and office equipment
• Gym equipment and locker rooms

Our customers rely on Envirosan—a hospital-grade disinfectant and sanitizer that kills 99.9% of bacteria and viruses. It’s versatile and effective for both healthcare and office settings.

For convenience, Roxton Disinfecting Wipes are perfect for daily use on high-touch surfaces.

How Are Cleaning, Sanitizing, and Disinfecting Different?

Each step in your cleaning routine plays a different role, and understanding when to use each one is key:

1. Cleaning

• Purpose: Removes visible dirt, dust, and debris from surfaces.
• Does it kill germs?: No — it physically removes them but doesn’t destroy them.
• When to use it: Always the first step before sanitizing or disinfecting. Use for general surface cleaning, spills, and everyday messes.

2. Sanitizing

• Purpose: Reduces the number of bacteria to safe levels, based on public health standards.
• Does it kill germs?: Yes — some types of bacteria.
• When to use it: Ideal for food prep areas, toys, and high-touch surfaces in lower-risk environments like break rooms or schools.

3. Disinfecting

• Purpose: Kills bacteria, viruses, and fungi on hard, non-porous surfaces.
• Does it kill germs?: Yes — most viruses and bacteria, including illness-causing pathogens.
• When to use it: After someone has been sick, or for high-traffic or high-risk areas like bathrooms, medical offices, and gyms.

Best Practices for All Three

To get the most out of your cleaning routine:

• Clean first: Dirt can block disinfectants from reaching germs.
• Follow contact times: Let sanitizers or disinfectants sit for the recommended duration.
• Use separate cloths: Avoid cross-contamination by using color-coded cloths for different areas.
• Read the labels: Not all cleaning products are sanitizers or disinfectants. Look for Health Canada or EPA-approved products when in doubt.
• Wear gloves and PPE: Especially when handling strong disinfectants.

For example, the Ultra Guard Citrus Disinfectant combines a fresh scent with powerful disinfecting properties, making it ideal for frequent-use spaces.

Which Should You Use—And When?

Here’s a general guide:

• Clean when dirt, spills, or visible residue are present.
• Sanitize after cleaning food prep areas or dishes.
• Disinfect when someone is sick or in high-traffic public spaces.

Each of these actions works together to create a safer environment—especially when paired with the right commercial-grade products.
