What is IPAC and Why Does It Apply to Dental Offices?
IPAC stands for Infection Prevention and Control. It's a framework of protocols designed to prevent the spread of infectious diseases in healthcare settings. Dental offices are classified as healthcare facilities in Ontario, which means they fall under the same infection control obligations as hospitals and clinics.
The RCDSO publishes its Infection Prevention and Control in the Dental Office standard, which all Ontario dentists must follow. This document covers everything from instrument sterilization to surface disinfection to waste disposal. The cleaning of environmental surfaces — floors, chairs, countertops, equipment — falls squarely within these requirements.
This means your professional cleaning company is not just a service provider. They are part of your IPAC program. If they don't understand the protocols, your practice is out of compliance regardless of what they clean.
RCDSO compliance responsibility rests entirely with the dental practice owner — not the cleaning company. If your cleaner uses the wrong products or wrong procedures, you bear the consequences during an inspection. This is why verifying your cleaning company's IPAC knowledge and documentation is not optional.
The 5 Core IPAC Cleaning Requirements for Ontario Dental Offices
1. Health Canada DIN-Registered Disinfectants
Every disinfectant used on clinical surfaces in a dental office must carry a Health Canada Drug Identification Number (DIN). This registration confirms the product has been evaluated and approved as effective against specific pathogens including bloodborne viruses.
Common DIN-registered products used in dental cleaning include intermediate-level disinfectants effective against Mycobacterium tuberculosis, HIV, and HBV. Your cleaning company must:
- Know which DIN-registered products are appropriate for each surface type
- Apply products at the correct dilution as specified on the label
- Allow the required contact (wet) time before wiping — skipping this defeats the disinfection entirely
- Use separate products for low-contact surfaces vs high-contact clinical areas where appropriate
Generic supermarket cleaners, non-DIN commercial cleaners, or diluting DIN products incorrectly are all IPAC violations — even if the surfaces look clean afterward.
2. Written Cleaning Logs
The RCDSO requires dental practices to maintain written records of their environmental cleaning procedures. An RCDSO inspector will ask to see these records during a practice assessment. Your cleaning logs must document:
Required Cleaning Log Content
Logs should be retained for a minimum of 2 years and stored where practice staff can access them if an inspector arrives. If your current cleaning company does not provide written logs after every service, this is a significant compliance gap.
3. Dirty-to-Clean Workflow
One of the most commonly misunderstood IPAC requirements is workflow sequencing. Dental office cleaning must always proceed from cleanest zones to most contaminated — never in reverse. Here's what this looks like in practice:
Non-Clinical Areas (Start Here)
- Reception desk and front counter
- Waiting room — chairs, tables, toys, magazines
- Hallways and common areas
- Staff room and kitchen
Semi-Clinical Areas
- Consultation rooms
- X-ray rooms (non-contact surfaces)
- Lab areas (non-instrument surfaces)
- Staff offices adjacent to clinical areas
Clinical Areas (Finish Here)
- Operatory surfaces — chair, delivery unit, light handles
- Bracket tables and instrument tray areas
- Suction handles and air/water syringe handles
- Sterilization area countertops and sinks
Restrooms (Always Last)
- Toilets, urinals, and surrounding areas
- Sinks and countertops
- Door handles and high-touch surfaces
- Floors with dedicated mop (never shared with clinical areas)
Critically, mops, cloths, and equipment used in clinical zones must never be used in non-clinical zones, and vice versa. Colour-coded equipment (separate colours per zone) is the standard method for preventing cross-contamination and is something inspectors look for.
4. Operatory Surface Disinfection Protocol
Each dental operatory must be disinfected after every patient, but end-of-day environmental cleaning by your professional cleaning company covers the full surface inventory:
- Dental chair — all upholstered surfaces, adjustment controls, armrests
- Dental light — handles (high-touch, must use barrier or disinfect), shade, arm
- Delivery unit — all surfaces, handpiece connections, instrument holders
- Bracket table — top surface, underside, supporting arm
- Air/water syringe — handle and trigger area
- Suction handles — HVE and saliva ejector holders
- Counter surfaces — all horizontal work surfaces in the operatory
- Cabinet handles and drawer pulls — high-touch, frequently missed
- Floor — mopped with clinical-zone dedicated equipment only
This is 15–20 individual surface points per operatory. For a 4-operatory practice, that's 60–80 discrete surface disinfection steps before the clinical cleaning is complete — which is why IPAC-compliant cleaning takes significantly longer than a standard office clean.
5. Sterilization Area Cleaning
The sterilization area in a dental office is one of the highest-risk zones for cross-contamination if not cleaned correctly. The RCDSO requires strict separation of dirty and clean instrument processing. Environmental cleaning of this area must:
- Clean the dirty (used instrument) side and clean (sterilized instrument) side separately and in sequence
- Disinfect countertops, sinks, and ultrasonic cleaner exteriors
- Clean autoclave exteriors (not interiors — that's clinical maintenance)
- Disinfect all high-touch surfaces including water faucet handles
- Use dedicated cloths that are not used elsewhere in the practice
Zone-by-Zone IPAC Cleaning Protocol — Ontario Dental Offices
IPAC requirements don't apply uniformly across a dental practice. The RCDSO classifies areas by risk level, and the cleaning protocol for each zone must match that classification. A cleaning company that treats the waiting room the same as an operatory is not IPAC-compliant — regardless of how clean the practice looks.
Chair, light handle, bracket table, unit surfaces, doctor/assistant stools
Instrument trays, counters, sinks, packaging area
Equipment surfaces, head, cone, control panel
Fixtures, floors, high-touch surfaces
Chairs, magazines/devices, reception counter, door handles
Counters, appliances, table, sink
Colour-Coded Cleaning Equipment — The RCDSO Standard
The RCDSO requires colour-coded cleaning equipment to prevent cross-contamination between clinical and non-clinical zones. This is one of the most commonly failed IPAC inspection points — many cleaning companies either aren't aware of the requirement or don't consistently implement it.
The standard colour-coding system used in Ontario dental offices:
- Red cloths and mops: Washrooms and toilet areas — highest contamination risk
- Yellow cloths: Clinical areas — operatories, sterilization room, x-ray room
- Green cloths: General areas — waiting room, reception, corridors
- Blue cloths: Low-risk surfaces — glass cleaning, fixtures in non-clinical areas
The colour-coding system must be documented in your written cleaning protocol — not just practiced. RCDSO inspectors look for the written protocol as evidence that the system is systematic rather than ad hoc. If your cleaning company uses colour-coded equipment but cannot produce a written protocol showing which colours apply to which zones, you are not fully compliant.
The Written Cleaning Log — What RCDSO Requires
The cleaning log is the documentary evidence that IPAC protocols were followed. It is the difference between telling an inspector "we follow IPAC" and proving it. RCDSO assessors examine logs during practice assessments, and incomplete or missing logs are a common compliance finding.
A compliant dental office cleaning log must record, for every cleaning visit:
- Date and time of the cleaning
- Name of the cleaning staff member who performed the work
- Areas cleaned — specific zones, not just "office cleaned"
- Products used — product name and DIN number for each clinical area
- Disinfectant dilution — the concentration applied (where applicable)
- Contact times observed — confirmation that products were allowed to act for the required time
- Signature or initials of the cleaning staff member
The log should be kept at the practice in physical or digital form and be immediately available for inspection. RCDSO assessments typically require at minimum the previous 12 months of cleaning records.
Every Zusashi dental cleaning visit includes a written service log documenting all of the above — date, staff, zones cleaned, products used by DIN number, and sign-off. Logs are provided to the practice at the end of each visit and can be stored in a binder at reception or forwarded digitally. Our dental clients use these logs directly for RCDSO compliance documentation.
IPAC Compliance for Specific Dental Procedures and Equipment
Beyond the standard zone cleaning, IPAC cleaning requirements interact with specific dental equipment and procedures in ways that affect what your cleaning company must know:
Dental Unit Waterlines
Dental unit waterlines (DUWLs) require regular flushing and monitoring for bacterial contamination. While waterline maintenance is typically handled by the dental team rather than the cleaning company, the surfaces around water outlets and the external components of the dental unit are cleaned by the cleaning company and must be treated with a compatible disinfectant that won't degrade tubing or fittings.
Suction and Evacuation Equipment
The exterior surfaces of suction equipment, traps, and evacuation systems are high-contamination clinical surfaces requiring intermediate-level disinfection. These are frequently missed by cleaning companies unfamiliar with dental environments — they look like generic plumbing components but are clinical surfaces under IPAC.
Portable Equipment
Portable equipment that moves between operatories — portable x-ray units, instrument trays, portable lights — requires disinfection after every use by clinical staff, and thorough disinfection by the cleaning company during the scheduled clean. Your cleaning protocol should specifically address portable equipment.
Computer Equipment in Clinical Areas
Computers, keyboards, and touchscreens in operatories are clinical-contact surfaces when used during patient treatment. They require disinfection with a product compatible with electronics — not the same intermediate-level disinfectant used on hard clinical surfaces. A cleaning company that uses the wrong product on clinical computers damages the equipment and may not achieve the required disinfection level.
The 2024 RCDSO IPAC Standard Update — What Changed
The RCDSO updated its Infection Prevention and Control in the Dental Office standard, with the most recent guidance emphasising several areas that directly affect cleaning requirements:
- Increased documentation requirements: The updated standard places greater emphasis on written evidence of compliance — logs, protocols, staff training records. Verbal assurances from cleaning companies are no longer considered sufficient.
- Cleaning company credentials: The RCDSO now explicitly recommends that dental practices verify that their cleaning company understands IPAC requirements specific to dental environments — not just general healthcare cleaning. A certificate from a generic healthcare cleaning course is not equivalent to dental-specific IPAC training.
- Risk-based zoning: The updated guidance reinforces the zone-by-zone risk classification approach, making the colour-coded equipment requirement more explicit.
- Environmental monitoring: For practices undergoing renovation or construction adjacent to clinical areas, additional environmental cleaning protocols apply. If your practice has undergone any work, confirm your cleaning company has adjusted protocols accordingly.
For the full RCDSO IPAC standard documentation, visit the Royal College of Dental Surgeons of Ontario website directly. The standard is updated periodically and the current version supersedes all previous guidance.
What RCDSO Inspectors Actually Check
The RCDSO conducts practice assessments that include a review of IPAC compliance. Based on what Ontario dental practices have reported, inspectors typically review the following related to environmental cleaning:
- Written cleaning logs — are they current, complete, and signed?
- Disinfectant product labels — are DIN numbers present and products appropriate?
- Cleaning equipment — are mops and cloths colour-coded by zone?
- Staff knowledge — can your staff explain what products are used and why?
- Written cleaning protocols — does the practice have a documented cleaning procedure?
- Physical inspection of surfaces — are high-touch areas actually clean?
RCDSO findings can result in a mandatory remediation plan, conditions on your certificate of registration, follow-up inspections, or in serious cases, suspension of practice. The RCDSO has significantly increased its inspection activity in recent years. "Our cleaner handles it" is not an acceptable response to an inspector — the protocols must be documented and verifiable.
How to Verify Your Cleaning Company is IPAC Compliant
Before signing any dental cleaning contract, ask these questions directly and expect written answers:
- "What Health Canada DIN-registered disinfectants do you use, and for which surfaces?" — They should be able to name specific products immediately.
- "Can I see a sample cleaning log from another dental client?" — If they don't provide logs, walk away.
- "How do you train staff specifically for dental office IPAC?" — Generic "we train our staff" is not enough. Ask for a training outline.
- "Do you use colour-coded equipment by zone?" — This is a basic IPAC requirement. No answer or confusion is a red flag.
- "Have you been through an RCDSO inspection at a client practice?" — Experience with inspections means they understand what compliance actually looks like under scrutiny.
At Zusashi Maintenance, we provide written cleaning logs after every visit, use Health Canada DIN-registered disinfectants on all clinical surfaces, and maintain full documentation available for RCDSO inspections.

Frequently Asked Questions
What are the IPAC cleaning requirements for dental offices in Ontario?
Ontario dental offices must follow RCDSO IPAC standards including: daily disinfection of all clinical surfaces with Health Canada DIN-registered disinfectants, written cleaning logs after every service, dirty-to-clean workflow procedures, colour-coded equipment by zone, and staff training documentation. These are inspected by the RCDSO during practice assessments.
What disinfectants are required for dental office cleaning in Ontario?
All clinical surface disinfectants must carry a Health Canada Drug Identification Number (DIN). These hospital-grade products must be used at the correct dilution with the required contact time per the product label. Generic or non-DIN cleaners are not acceptable for operatories, sterilization areas, or any clinical surfaces.
What is the dirty-to-clean workflow in dental office cleaning?
Cleaning must always progress from least contaminated to most contaminated zones — non-clinical areas first, clinical operatories next, restrooms last. Staff must never return to a clean zone after working in a contaminated one, and equipment like mops and cloths must be dedicated to specific zones and never shared across zones.
What happens if a dental office fails an RCDSO inspection for cleaning?
Consequences range from a mandatory written remediation plan and follow-up inspections to conditions placed on your certificate of registration. In serious cases, suspension of practice is possible. The responsibility falls on the dental practice owner, not the cleaning company — making proper documentation and genuine IPAC compliance non-negotiable.
Do I need written cleaning logs for my dental office?
Yes. The RCDSO requires documentation of cleaning procedures that can be produced during an inspection. Logs must record the date, time, areas cleaned, disinfectants used (product name, DIN, dilution, contact time), and the cleaning staff member's signature. Retain logs for a minimum of 2 years.
