A precise walk through 21 CFR Parts 211, 111 and 117 on cleaning and sanitation, what a compliant SOP and log contain, and where inspections most often find gaps.
Why is cleaning in a GMP facility different from standard janitorial?
GMP cleaning is governed by FDA regulations that require written procedures, documented cleaning schedules, controlled chemistry, and records tied to specific equipment and dates — not just visibly clean surfaces. The regulation cares about traceability and contamination prevention as much as it cares about the result looking clean.
In a standard office or warehouse, 'clean' is judged by appearance and basic sanitation. In a drug, dietary supplement, or food manufacturing facility, cleaning is a documented control point in the quality system — it exists to prevent contamination that could alter a product's safety, identity, strength, quality or purity. That distinction drives every requirement below: FDA's regulations don't just ask that a surface be wiped, they ask that the wiping follow a written procedure, use appropriate agents, and leave a record someone can review during an audit or inspection. See GMP and regulated facilities for how this shapes day-to-day service, and janitorial services for the base recurring program these SOPs get layered onto.
This guide paraphrases what the relevant regulations in Title 21 of the Code of Federal Regulations actually require. It does not describe Nexara's own certifications or registration status — a contract cleaner supporting a GMP facility is not itself an FDA-registered establishment, and no cleaning company should claim to be 'GMP certified' by FDA, because FDA does not certify companies. What a contract cleaner can do is operate to the facility's documented SOPs and support the facility's own compliance obligations.
What does 21 CFR Part 211 require for cleaning in drug manufacturing?
21 CFR 211.56 requires buildings used in drug manufacturing to be maintained in a clean, sanitary condition under written procedures with defined cleaning schedules, methods, equipment and materials. 21 CFR 211.67 requires equipment to be cleaned and, where appropriate, sanitized or sterilized at intervals that prevent contamination, under written procedures — with cleaning, maintenance and inspection records kept per 21 CFR 211.182.

For a contract cleaner, the practical implication is that cleaning tasks touching production-adjacent equipment or surfaces named in the facility's validated cleaning procedure have to follow that procedure exactly — not a general best-practice version of it — and the completed work has to be logged in a way the facility's own quality system can retrieve later. This is a different working model than routine janitorial, where a task either got done or didn't with no formal record required.
What does 21 CFR Part 111 require for dietary supplement facilities?
21 CFR 111.15 requires cleaning compounds and sanitizing agents to be free of microorganisms of public health significance and safe under the conditions of use, with toxic materials identified and stored to prevent contamination. 21 CFR 111.27 requires equipment and utensils to be designed for adequate cleaning, and to be cleaned, sanitized and maintained as necessary, including being taken apart for thorough cleaning when needed.
Key dietary supplement cleaning citations, 21 CFR Part 111
21 CFR 111.15 — Sanitation requirements for physical plant and grounds
- What it covers
- Cleaning compounds and sanitizing agents
- Core requirement
- Compounds and agents must be free from microorganisms of public health significance and safe/adequate for their use; toxic materials must be identified and held/stored to protect against contamination of components, supplements, or contact surfaces
21 CFR 111.27 — Equipment and utensils
- What it covers
- Design, cleaning and maintenance of equipment
- Core requirement
- Equipment/utensils must be designed, constructed and installed to allow adequate cleaning and proper maintenance; all contact surfaces must be cleaned and sanitized as necessary, disassembled as needed for thorough cleaning, and low-moisture contact surfaces must be dry and sanitary when in use
| Citation | What it covers | Core requirement |
|---|---|---|
| 21 CFR 111.15 — Sanitation requirements for physical plant and grounds | Cleaning compounds and sanitizing agents | Compounds and agents must be free from microorganisms of public health significance and safe/adequate for their use; toxic materials must be identified and held/stored to protect against contamination of components, supplements, or contact surfaces |
| 21 CFR 111.27 — Equipment and utensils | Design, cleaning and maintenance of equipment | Equipment/utensils must be designed, constructed and installed to allow adequate cleaning and proper maintenance; all contact surfaces must be cleaned and sanitized as necessary, disassembled as needed for thorough cleaning, and low-moisture contact surfaces must be dry and sanitary when in use |
The regulation's own definition of "sanitize" is worth knowing precisely: treating a cleaned surface by a process effective in destroying vegetative cells of microorganisms of public health significance and substantially reducing other microorganisms, without adversely affecting the product or its safety. That definition is the standard a facility's SOPs should be written against, and it's stricter than a general-purpose disinfectant claim on a retail cleaning product label.
What does 21 CFR Part 117 require for food facility cleaning?
21 CFR 117.35 requires food facilities to be maintained in a clean, sanitary condition, with cleaning and sanitizing conducted in a way that protects against allergen cross-contact and contamination of food, food-contact surfaces and packaging. Cleaning compounds and sanitizing agents must be free of undesirable microorganisms and safe under the conditions of use, and cleaned equipment must be stored to protect against contamination.
- **Cleaning compounds and sanitizing agents** must be free from undesirable microorganisms and safe/adequate for their intended use; toxic materials must be identified, held and stored to protect against contamination of food, food-contact surfaces or packaging.
- **Food-contact surfaces** must be cleaned as frequently as necessary to protect against allergen cross-contact and food contamination — low-moisture contact surfaces must be dry and sanitary when in use; wet-processing surfaces require cleaning and sanitizing before use and after any interruption.
- **Non-food-contact surfaces** of equipment must be cleaned in a manner and frequency that prevents allergen cross-contact and contamination of food, food-contact surfaces and packaging materials.
- **Storage of cleaned equipment and single-service articles** must protect food-contact surfaces from allergen cross-contact and contamination between uses.
Allergen cross-contact is the requirement most likely to surprise a facility manager coming from a non-food background: it isn't enough for a surface to look clean and be pathogen-free — the cleaning and sanitizing procedure has to actively prevent one product's allergens from transferring onto equipment or surfaces used for a different product. That changes tool and rag management (color-coding, dedicated equipment by zone) from a nice-to-have into a documented requirement in many facilities' own food safety plans.
What does a compliant cleaning SOP and log actually need to contain?
A compliant SOP names the responsible role, the exact cleaning schedule and method, the equipment and materials used, and any sanitizing agent with its required contact time — while the accompanying log records the date, time, area or equipment, product/lot number where relevant, and the initials of who performed and verified the work.
- 01
Responsibility
Name the role (not just "staff") accountable for each cleaning task, matching what 21 CFR 211.56(b) and 211.67(b) both require for their respective regulated environments.
- 02
Schedule and method
State the frequency and the specific method — spray-and-wipe, mop-and-rinse, CIP (clean-in-place) — rather than a general instruction to "clean as needed."
- 03
Materials and agents
Name the approved cleaning compound or sanitizing agent, its required concentration or dilution, and contact time where sanitizing is required.
- 04
Verification before use
For equipment cleaning specifically, require a documented inspection for cleanliness immediately before the equipment goes back into use — this is explicit in 21 CFR 211.67(b)(6).
- 05
The log entry itself
Date, time, area or equipment ID, product/lot number where applicable, and the signature or initials of the person who performed the work and, separately, who verified it.
What is a contract cleaner's actual responsibility in a regulated facility?
A contract cleaner's responsibility is to execute the facility's documented cleaning SOPs precisely, keep the required logs accurately and on time, use only approved chemistry at approved concentrations, and flag any deviation immediately rather than quietly correcting it and moving on — deviations in a regulated environment need to be visible to the facility's quality team, not smoothed over.
This is a meaningfully different working relationship than standard janitorial. In a regulated facility, the cleaning crew is functioning as an extension of the client's own quality system for the hours they're on site, which means training on the facility's specific SOPs (not a generic equivalent), strict adherence to zone-specific equipment to prevent cross-contamination, and a documented chain of custody for any deviation, no matter how minor it looks. High-level dusting of overhead pipe runs and racking — see high dusting — follows the same rule: it's scheduled and logged against the facility's SOP, not done on a generic cadence. See life sciences and laboratories and manufacturing and warehouse for how this shapes the service model day to day.
What cleaning-related findings show up most often in FDA inspections?
Historical FDA inspectional-observation data shows equipment cleaning and maintenance under 21 CFR 211.67 as the single most frequently cited hygiene-related deviation, followed by inadequate cleaning and maintenance records under the same section, and missing or incomplete written sanitation procedures under 21 CFR 211.56.
An analysis of FDA inspectional observations from fiscal year 2010 found over 120 hygiene-related deviations across the categories tracked, with 21 CFR 211.67(a) — cleaning, sanitizing and maintenance — accounting for the largest single share (61 observations), followed by 21 CFR 211.67(c) records deficiencies (29 observations), and 21 CFR 211.56(b) missing sanitation procedures (13 observations). While that specific dataset is now dated, the pattern it describes — documentation and procedural gaps outnumbering visible dirt — is consistent with how these regulations are written: they weight written procedures and records as heavily as the physical cleaning itself. A facility building or auditing its own cleaning SOPs against this pattern should also see the general janitorial scope of work template for how task, frequency and inspection standard get documented at the room level before compliance-specific logging is layered on top.
- Cleaning performed without a written procedure specific enough to be repeatable by different staff on different shifts.
- Equipment cleaning logs missing entries, signatures, or the specific product/lot number tied to the cleaning event.
- Sanitation procedures that exist but don't name the schedule, method, or materials in enough detail to audit against.
- Cross-contamination risk from shared equipment or tools used across zones without a documented cleaning-between-use step.
- No documented inspection for cleanliness immediately before equipment returns to use.
Common questions.
Is Nexara FDA registered or GMP certified?
FDA does not certify cleaning companies, and Nexara does not claim FDA registration or any compliance certification. What a contract cleaner in a regulated facility does is execute that facility's own documented, validated SOPs and logging requirements precisely — the regulatory responsibility for the overall program stays with the facility.
What's the difference between cleaning and sanitizing in a GMP context?
Cleaning removes visible soil and debris; sanitizing is a separate step that reduces microorganisms to a safe level using an agent at a specific concentration and contact time. FDA's dietary supplement regulation (21 CFR 111.3) defines sanitizing specifically as destroying vegetative cells of public-health-significant microorganisms without harming the product.
Does every cleaning task in a regulated facility need to be logged?
No — the logging requirement in 21 CFR 211.182 applies specifically to major equipment cleaning, maintenance and use, tied to individual equipment logs. Routine facility cleaning under 21 CFR 211.56 needs written procedures and assigned responsibility, but the equipment-use-log requirement is narrower and equipment-specific.
Can the same mop or rag be used across different zones in a GMP or food facility?
Generally no, without a documented cleaning-between-use protocol, because doing so risks cross-contamination between zones or products — a risk 21 CFR 117.35 addresses directly for allergen cross-contact in food facilities. Color-coded, zone-dedicated tools are a common way facilities control this.
What agencies or documents govern disinfectant selection in a regulated facility?
Selection is governed by the facility's own validated SOPs, which typically specify EPA-registered disinfectants appropriate to the surface and microorganism risk. This guide does not cite a specific rotation standard beyond what a facility's own SOP defines, since disinfectant rotation practices vary by facility and product risk.
Who is responsible if an FDA inspector finds a cleaning deficiency — the facility or the contract cleaner?
Regulatory responsibility rests with the facility operating under FDA's regulations, not the contract cleaning company. That's exactly why a contract cleaner's job is disciplined execution of the facility's own SOPs and logs, with any deviation reported immediately rather than handled informally.
Do these regulations apply to a cleaning company's own internal operations?
No. 21 CFR Parts 111, 117 and 211 govern the regulated manufacturer's facility and quality system. A contract cleaning company isn't itself the regulated entity — its obligation is to perform work according to the client facility's SOPs, not to hold its own FDA registration.
What's the single most common documentation gap FDA inspectors cite related to cleaning?
Historically, equipment cleaning and maintenance records under 21 CFR 211.67(c) and 211.182 — logs that are missing, incomplete, or not tied to a specific date, product and lot number — are among the most frequently cited gaps, often outnumbering findings about visible dirt or contamination itself.
