How to Prevent Cross-Contamination in Care Home Laundry Rooms

Laundry is more than just a cleaning task in care homes — it’s a frontline defence against infection. Without the right controls in place, laundry rooms can become hotspots for cross-contamination, putting both residents and staff at risk.

In this audit-ready guide, we outline the practical controls inspectors expect to see in care home laundry rooms — and the steps your team can implement to prevent infection spread, demonstrate compliance, and reduce regulatory risk.

Why Laundry Cross-Contamination Matters

In a care environment, soiled linens often contain pathogens like MRSA, norovirus, or C. difficile. If laundry isn’t handled correctly, these organisms can spread via:

• Contaminated surfaces or equipment

• Improper handling of clean/dirty items

• Poor PPE use or hand hygiene

• Airborne particles from uncovered laundry

Cross-contamination not only increases infection risks but may also lead to CQC non-compliance during inspections.

What Inspectors Look for in Care Home Laundry Rooms

During CQC inspections, laundry areas are assessed as part of infection prevention and control. Inspectors typically look for:

• Clear physical or procedural separation of clean and dirty workflows

• Evidence of thermal or chemical disinfection processes

• Staff training records relating to laundry hygiene

• Documented machine maintenance and servicing

• Correct use of colour-coded segregation systems

• Safe storage of clean linen away from contaminated zones

If these controls are not clearly visible — or cannot be evidenced — laundry rooms are often identified as compliance risks.

1. Separate Dirty and Clean Zones

Designate clear zones within the laundry room:

• Dirty area: For receiving and handling soiled laundry

• Clean area: For storing and sorting freshly laundered items

Ideally, these should be physically separated or at least have directional flow to avoid overlap. Never process clean and dirty laundry at the same time.

2. Use Colour-Coded Laundry Bags

Use water-soluble red bags for infected items, white or blue bags for general soiling, and store clean laundry in separate containers.

Colour coding helps staff follow infection control protocols without second-guessing. It also simplifies training.

3. Clean Machines and Surfaces Regularly

Limescale, detergent residue, and biofilm can build up in machines. Clean:

• Inside of washers and dryers weekly

• Handles, doors, and sorting surfaces daily

• Floors and high-contact points as part of your routine cleaning schedule

Products like Eclipse Scale Breaker+ can help remove limescale while disinfecting and deodorising.

4. Don’t Overload or Underload Machines

Overloaded washers may not allow proper agitation or rinsing. Underloaded cycles waste energy and may not reach proper thermal disinfection temperatures.

Always follow machine load guidelines to ensure effective cleaning. Incorrect loading, rewashes, and energy waste can significantly increase your cost per wash in care homes, particularly when labour and textile wear are factored in. Our guide to calculating and reducing laundry cost per wash explains how process inefficiencies directly affect overall laundry spend.

5. Follow Thermal or Chemical Disinfection Standards

Comply with HTM 01-04 or similar care guidance:

• Thermal disinfection: 71°C for 3 minutes, or 65°C for 10 minutes

• Chemical disinfection: If lower temps are used, ensure detergents are certified to meet hygiene standards (e.g. EN 1276 or EN 1650)

• Keep written records of wash temperatures, chemical dosing systems, and servicing schedules. Being able to demonstrate validated disinfection processes is just as important as carrying them out.

Using an auto-dosing system can help maintain correct chemical levels consistently.

6. Wear PPE and Follow Hand Hygiene

Laundry staff should wear gloves and aprons when handling soiled items — and remove them before touching clean areas. Handwashing is essential between each task.

Train staff to treat laundry as potentially infectious at all times, especially in outbreak situations.

7. Train and Supervise Staff

Cross-contamination often happens due to inconsistent habits. Regular refresher training helps reinforce:

• Correct use of PPE

• Separation of clean and dirty processes

• Reporting of spills or machine faults

• Use visual posters in laundry areas and include laundry hygiene in induction programmes. 

Inspectors may ask staff to explain laundry procedures during visits, so consistent training and supervision are essential.

Unsure Whether Your Laundry Process Would Pass Inspection?

Even small gaps in zoning, documentation, or chemical dosing can lead to compliance concerns during inspection.

We can review your current laundry setup and identify practical improvements to reduce infection risk and strengthen audit readiness.

Audit-Ready Checklist: Preventing Cross-Contamination in Care Home Laundry

• Clear separation between clean and dirty areas

• Colour-coded laundry bags and bins

• Proper PPE and hand hygiene

• Thermal or chemical disinfection

• Auto-dosing for correct detergent use

• Regular machine and surface cleaning

• Staff training and supervision

• Written documentation of laundry procedures and training

• Records of machine servicing and temperature validation

Strengthen Your Laundry Infection Control Before Inspection

Preventing cross-contamination in care home laundry rooms isn’t just good practice — it’s a compliance requirement.

If you want reassurance that your zoning, disinfection methods, and staff procedures align with current expectations, we can help you sense-check your setup and identify any risk areas.
