When it comes to professional cleaning, not all jobs are created equal. Different spaces—and different situations—require different levels of care.

That’s why cleaning professionals often refer to “classes of cleaning.” These classifications help identify the type of cleaning required, the level of contamination or dirt involved, and the right methods or products to use.

At Right The 1st Time, we use this knowledge to tailor every service—whether it’s a quick tidy-up or a full deep clean—so your home always gets the right level of attention.

Let’s look at the five main classes of cleaning and what they mean.

1. Class 1: Routine or Maintenance Cleaning

This is your everyday cleaning—the kind that keeps your home looking neat and welcoming. It focuses on visible surfaces and frequently used areas.

Typical Tasks Include:

• Dusting surfaces

• Sweeping, vacuuming, and mopping

• Wiping down countertops

• Cleaning bathrooms and kitchens

• Emptying trash

Purpose: Maintain appearance, reduce surface dust and bacteria, and prevent buildup.

👉 Ideal for: Weekly or biweekly recurring cleaning services.

2. Class 2: Deep or Detailed Cleaning

This goes a step beyond the basics. Deep cleaning targets areas that don’t get attention during routine cleanings—like baseboards, appliances, and hidden corners.

Typical Tasks Include:

• Scrubbing grout, sinks, and tubs

• Washing cabinet fronts and doors

• Cleaning baseboards and window sills

• Wiping ceiling fans and vents

• Cleaning inside appliances

Purpose: Eliminate built-up dirt and grime for a truly refreshed space.

3. Class 3: Sanitization and Disinfection Cleaning

This level focuses on killing germs and bacteria—especially in high-touch or high-traffic areas like kitchens, bathrooms, offices, and playrooms.

Typical Tasks Include:

• Disinfecting doorknobs, switches, and handles

• Sanitizing sinks, toilets, and countertops

• Using EPA-approved cleaning agents

Purpose: Reduce harmful pathogens and maintain a hygienic environment.

👉 Especially important for homes with kids, elderly residents, or immunocompromised family members.

4. Class 4: Restoration or Post-Event Cleaning

This class applies to cleaning after major events—like renovations, water leaks, smoke, or mold contamination. It involves specialized tools, PPE, and training.

Typical Tasks Include:

• Removing construction dust and debris

• Treating stains, soot, or residue

• Sanitizing after water or fire damage

Purpose: Restore the property to a safe, livable condition.

While Right The 1st Time focuses on residential deep cleaning, we can help recommend trusted restoration partners if needed.

5. Class 5: Specialized or Hazard Cleaning

This is the highest level of cleaning and typically handled by trained professionals in commercial, medical, or hazardous environments.

Typical Tasks Include:

• Biohazard cleanup (bloodborne pathogens, mold, etc.)

• Laboratory or healthcare sterilization

• Industrial or environmental cleanup

Purpose: Protect health and safety through rigorous decontamination protocols.

While Right The 1st Time focuses on residential deep cleaning, we can help recommend trusted restoration partners if needed.
