Care Home Cleaning: Infection Control Essentials

What are the core infection control essentials for care homes?

Care home cleaning infection control is a specialist discipline that sits between domestic hygiene and clinical-grade disinfection — governed by colour-coded equipment, documented cleaning schedules, correct norovirus protocol, and consistent high-touch surface cleaning.

Care homes are somebody's actual home, not a sterile clinical environment — yet they house some of the most infection-vulnerable people in the country, often living in close proximity, sharing communal spaces and staff, with residents who may not always be able to manage their own hygiene independently. Getting infection control right here is the difference between a manageable cold going round and a norovirus outbreak that closes a home to visitors for weeks.

Why do care homes carry a distinct infection risk?

Care homes require their own infection control approach because neither domestic cleaning nor acute hospital protocols fully address their unique risk profile. Residents are frequently older, often living with multiple health conditions, and may have weakened immune systems that make them considerably more vulnerable to infections that a younger, healthier person would shrug off easily.

The structure of communal living — shared dining rooms, lounges, activity spaces, and staff moving between multiple residents across a single shift — creates genuinely elevated transmission risk built into the basic operating model of a care home. This is precisely why infection control in this setting must be systematic and well-documented, rather than left to individual judgement on any given day. Our healthcare cleanliness standards guide covers the equivalent framework for NHS settings, where similar principles apply at a larger scale.

The colour-coding system, explained

The colour-coding system prevents cross-contamination by ensuring cleaning equipment is dedicated to specific zones and never transferred between them. CQC inspectors specifically look for staff who can explain the system correctly — not simply follow it by habit.

Colour	Area
Red	Bathrooms and toilets
Blue	General areas (lounges, corridors, bedrooms)
Green	Kitchens and food preparation
Yellow	Isolation rooms (residents with a known or suspected infection)

The logic is straightforward but important: using the same cloth or mop across a toilet and then a dining table, even with good intentions, creates a genuine cross-contamination pathway that colour separation eliminates entirely.

This system works precisely because it does not rely on memory or in-the-moment judgement calls. Cleaning and care staff — even those who change areas or shift patterns regularly — all work to the same standard without needing to think it through each time. This makes both day-to-day consistency and periodic auditing considerably easier to maintain across a whole team.

What does CQC expect to see for infection control in care homes?

CQC inspectors expect documented evidence that infection control is proactive and systematic, not reactive. Infection prevention and control falls under Regulation 12 of the Health and Social Care Act, benchmarked against the Health and Social Care Act 2008: Code of Practice on the prevention and control of infections — commonly known as the Hygiene Code — which requires providers to demonstrate they are actively preventing infection rather than simply responding to problems after they arise.

In practice, this means inspections go well beyond a visual check of whether a room looks clean. Inspectors will typically ask to see daily and weekly cleaning logs, audit reports, and documented risk assessments. They may also ask staff directly to explain the colour-coding system, and check storage areas to verify that documented practices match what is actually happening on the ground.

This documentation requirement is not bureaucratic box-ticking. A written schedule makes gaps immediately visible rather than relying on staff memory across shift patterns, and it provides a care home with genuine evidence of due diligence if an infection incident does occur and requires investigating afterwards.

High-touch surfaces: where infection spreads fastest

High-touch surfaces — including door handles, taps, light switches, handrails, and toilet flush handles — are the primary transmission points for pathogens in care home settings and require cleaning at least daily as a baseline. Daily cleaning covers all surfaces and touchpoints; a weekly deep clean should additionally cover bed frames, windowsills, and behind furniture.

These surfaces are touched by multiple people, multiple times a day, often by hands that have not been washed in between. Standard guidance calls for daily cleaning as a minimum, with frequency stepped up considerably during any period of elevated infection risk — a seasonal flu spike, a confirmed case in the home, or a period when local infection rates are known to be elevated.

This is not a fixed, unchanging schedule. It is designed to flex in response to actual risk levels, which is part of why ongoing awareness of local infection trends matters as much as the base cleaning routine itself.

How to manage a norovirus outbreak in a care home

During a norovirus outbreak, surfaces must be cleaned to remove organic soiling first, then disinfected with a 0.1% (1,000ppm) hypochlorite solution — in that order. Because norovirus spreads so efficiently through contaminated surfaces and requires only a tiny viral load to cause infection, this sequencing is critical.

During a suspected outbreak, toilets and bathrooms should be cleaned at least twice a day. Horizontal surfaces should be cleaned and disinfected up to two metres beyond any visibly contaminated area, since norovirus can travel further than it appears to.

Disinfectant applied directly onto organic matter — faeces, vomit, or general grime — does not work effectively, because the organic material can physically shield pathogens from the disinfecting agent. Correct technique always removes visible soiling first, then applies the disinfectant to the now-clean surface to kill any remaining pathogens.

Spills during an active outbreak need immediate attention using the correct products and PPE, rather than being left even briefly — every additional minute a contaminated surface remains untreated represents additional transmission risk.

Outbreak response also typically includes broader measures beyond cleaning alone:

• Limiting movement between different areas of the home
• Cohorting staff to specific zones where practical, to reduce cross-contact
• Tightening the whole infection control routine, not simply increasing the frequency of standard tasks

Communication is as important as the cleaning itself during an outbreak. Families and visitors need clear, timely information about any restrictions, and staff across all shifts need to understand exactly what has changed in the cleaning protocol — not just the shift that was on duty when the outbreak was first identified. A well-managed outbreak is typically one where every member of staff, regardless of when they are working, can accurately explain the current protocol without needing to check.

PPE: matching protection to actual risk

PPE in care homes should be matched to the specific risk level of each task — neither used uniformly across all situations, nor omitted in genuinely high-risk contact. The right approach requires staff to understand what protection each task actually requires:

• Masks and eye protection are appropriate for close personal contact with a symptomatic resident where there is a risk of splashing or droplet contact — during personal care involving coughing or vomiting, for example.
• Gloves and aprons are appropriate wherever contact with body fluids, non-intact skin, or continence care is likely.
• Critically, PPE must be changed between residents and between different tasks — not worn continuously across a shift as if it were general protective clothing.

Over-use in low-risk situations wastes resources and can create false confidence, while under-use in genuinely high-risk contact defeats the purpose of having PPE available at all.

Staff illness policy: the overlooked infection control essential

A care home's staff illness policy is a direct infection control measure — a well-cleaned building cannot protect residents if an infected staff member continues working through symptoms. Standard guidance is clear that anyone experiencing relevant symptoms should remain away from work, and should not be involved in food handling until at least 48 hours after symptoms have fully resolved.

This policy only works if it is genuinely supported in practice. Staff need to feel able to report symptoms and stay home without facing unreasonable pressure to attend anyway, particularly during periods when the home is already short-staffed. A strong written policy that is not followed under operational pressure provides no real protection — which is worth keeping in mind when reviewing how infection control policies translate into day-to-day staffing decisions.

Building genuine consistency, not just documented policy

Sustainable care home infection control depends on consistent, actively managed practice — not a policy folder reviewed primarily at inspection time. Everything above works properly only when it is applied consistently, not merely written down and referred to occasionally. This means:

• Proper induction training for new staff on colour-coding and PPE use specifically — not just a general mention during broader onboarding.
• Periodic refresher training for existing staff, since infection control practices and guidance do get updated over time.
• Regular internal audits, checking that documented schedules match actual practice on the ground — catching gaps before an external inspection does.
• A named infection control lead, accountable for keeping policy current with the latest UKHSA and CQC guidance, coordinating training, and acting as the first point of contact when an outbreak begins to develop.

Spreading accountability thinly across a whole team without one clear owner tends to mean gaps go unnoticed until they have already become a larger problem than an early intervention would have required.

A care home that treats infection control as a living, actively managed system — rather than a compliance exercise — is the one that keeps outbreaks smaller and shorter when they inevitably do occur.
