Clean Plates, Clean Reputation: Why Hygiene Matters in Every Eating Establishment

There are some things a customer simply does not want to see when eating in a café, pub or restaurant.

My wife and I recently witnessed a particularly worrying example. 

We had already ordered and finished our meals and drinks when we noticed a member of staff washing used cups, plates and glasses under a running cold-water tap, using the same sponge-on-a-stick for everything.

What made the situation even more extraordinary was that she was standing next to a modern commercial dishwashing machine.

Whatever the explanation, from a customer's perspective it immediately raises questions about hygiene, and once customers start wondering whether the crockery and glasses are properly clean, confidence in the entire establishment can disappear remarkably quickly.

Hygiene Is a Business Issue

Cleanliness isn't simply something for the kitchen staff to worry about. It is fundamental to running a successful hospitality business.

Customers reasonably expect the plate beneath their sandwich, the cup containing their coffee and the glass holding their drink to have been properly cleaned.

Commercial dishwashers exist for a reason. Correctly operated and maintained, they provide a controlled and repeatable cleaning process. Handwashing items under running cold water with the same cleaning implement does not inspire anything like the same confidence.

There is another important consideration: cross-contamination.

Using the same sponge or brush repeatedly on different dirty items can potentially transfer contamination from one surface to another. Cleaning equipment itself therefore needs appropriate cleaning, replacement and management.

Customers Notice More Than You Think

Business owners sometimes underestimate just how observant customers can be.

People notice sticky tables, dirty menus, stained cutlery, overflowing bins, unpleasant toilets and staff handling food without appropriate attention to hygiene. They also notice what happens behind the counter.

And today, one customer's observation can quickly become everybody's observation.

A poor hygiene experience can result in negative reviews on Google, Tripadvisor and social media. A photograph or video can spread even further.

Years of work building a good local reputation can be undermined surprisingly quickly.

Why Wasn't the Dishwasher Being Used?

The incident we witnessed also raises an important management question.

Why would an employee wash crockery and glasses in this fashion when a commercial dishwasher was immediately beside her?

Perhaps the machine was temporarily faulty. Perhaps the employee hadn't been trained to operate it. Perhaps someone was trying to save electricity. Or perhaps poor practices had simply become normalised.

Whatever the reason, management needs to know.

Installing expensive commercial equipment achieves very little if employees aren't trained to use it properly or managers don't ensure agreed hygiene procedures are actually followed.

Training Should Never Be Assumed

Hospitality businesses often experience high staff turnover, which makes good induction and refresher training particularly important.

Managers should ensure employees understand not merely what they are expected to do, but why the procedures matter.

That includes appropriate procedures for washing crockery and utensils, hand hygiene, cleaning food-contact surfaces, preventing cross-contamination, waste disposal and cleaning toilets and customer areas.

Managers should also periodically observe what is happening during an ordinary working day rather than assuming written procedures are being followed.

Cleanliness Builds Customer Confidence

There's also a positive business case for excellent hygiene.

Walking into a spotless café or restaurant immediately creates confidence. Clean tables, sparkling glasses, properly presented cutlery and well-maintained toilets quietly tell customers: we care about standards here.

That impression extends to the food.

Customers cannot see everything happening inside a kitchen, so the cleanliness they can see becomes an important indicator of the standards they cannot.

And don't underestimate toilets. Customers often judge the cleanliness of an entire establishment by the condition of its lavatories. If they're dirty, some diners inevitably wonder what the kitchen looks like.

The Cost of Getting It Wrong

Poor hygiene can ultimately cost considerably more than the few minutes supposedly saved by taking shortcuts.

There are potential complaints, refunds, negative reviews, lost repeat business and reputational damage. More serious failures can involve foodborne illness and intervention from environmental health authorities.

For independent cafés and restaurants in particular, reputation is immensely valuable.

One unhappy customer might represent considerably more than the loss of one meal. If that customer would otherwise have visited every fortnight for several years, the lifetime value of their business could run into hundreds or thousands of pounds.

Managers Need to Look Through Customers' Eyes

Every hospitality manager should occasionally walk through their establishment pretending they are visiting for the first time.

Look at the entrance. Look underneath tables. Pick up a menu. Examine the glasses. Visit the toilets. Watch how tables are cleared and cleaned. Observe how crockery is handled.

And, importantly, watch what staff do when they don't realise management is watching.

The café incident my wife and I witnessed demonstrates why this matters.

A commercial dishwasher was sitting right beside the employee, yet cups, glasses and plates were being washed under running cold water with the same sponge-on-a-stick.

Whether that represented a one-off mistake or established practice, as customers we couldn't possibly know.

And that is precisely the problem.

In hospitality, customers shouldn't have to wonder whether something is clean.

They should be able to take it for granted.

For café, pub and restaurant owners, cleanliness isn't merely good hygiene. It's good management, good customer service and, ultimately, good business.

Cooler “Eco” Dishwasher Cycles in Commercial Kitchens: A Hidden Infection Risk for Vulnerable People

Across the UK, commercial kitchens are under intense pressure to cut energy use. 

Rising utility bills, net-zero commitments, and sustainability policies mean that eco settings on commercial dishwashers are increasingly treated as the default rather than the exception.

In many workplaces, that change is well-intentioned. In some environments, it may even be entirely appropriate.

But in others, particularly where vulnerable people are being fed or cared for, cooler, lower-energy dishwasher cycles can quietly increase the risk of infection if they are used without proper controls, validation, and staff training.

This is not an argument against sustainability. It is an argument for risk-based decision-making, not blanket cost-cutting.

Why commercial dishwashing is a safety issue, not just a cleaning task

In a domestic setting, dishwashing is mostly about appearance and convenience. In a commercial environment, it is part of food safety and infection control.

Commercial warewashing relies on a balance of four factors:

Temperature (wash and final rinse)

Chemicals (detergent, rinse aid, sometimes sanitiser)

Mechanical action (spray pressure and coverage)

Time (adequate contact at the right conditions)

Traditional commercial systems often rely heavily on thermal disinfection, particularly a hot final rinse, to reduce microbial contamination on plates, cutlery, cups, and utensils.

When eco modes reduce temperatures, shorten effective contact, or slow heat recovery, that balance changes—and unless the system has been properly validated, hygiene performance may fall without being obvious.

Who is most at risk?

Lower wash temperatures don’t usually affect the healthiest customers first. The people most at risk are those with reduced ability to fight infection, including:

Residents of care homes and supported living

Hospital patients, including outpatient and day-care services

Nurseries and early years settings

People receiving meals on wheels or community food provision

Individuals with compromised immune systems, chronic illness, or advanced age

For these groups, even low-level contamination can contribute to outbreaks of gastrointestinal illness or secondary infections—especially when combined with other pressures on staffing, cleaning, and food handling.

How eco dishwasher settings can create real-world problems

1. Reduced thermal disinfection

Many commercial machines are designed so that the final rinse temperature plays a key role in hygiene. If eco mode lowers that temperature—or if the machine struggles to reach it during busy service—the disinfection step may be weakened.

2. Poor removal of grease and protein soils

Cooler water is less effective at breaking down fats and proteins. Combined with:

Heavy soiling

Inadequate scraping

Overloaded racks

Blocked spray arms or filters

this can lead to biofilm build-up inside the machine and on items that look clean but are not hygienically safe.

3. Greater dependence on perfect chemical dosing

Eco cycles often rely on chemistry to compensate for lower temperatures. If:

Detergent dosing is incorrect

Rinse aid runs out

Pumps are poorly calibrated

Staff use the wrong products

cleaning performance can drop sharply with little visual warning.

4. Pressure during peak service

Eco modes may work on paper, but struggle in practice when:

Incoming water is cold (common in winter)

The machine cannot recover heat between loads

Back-to-back cycles are run continuously

This leads to inconsistent results—some loads fine, others borderline.

5. The cultural risk: “saving energy at all costs”

Perhaps the biggest danger is behavioural. When “eco” becomes a managerial priority without clear boundaries, it can encourage:

Skipped pre-scraping

Infrequent filter cleaning

Ignored warning lights or alarms

Hand-drying wet items with tea towels

Reluctance to report faults

That is where infection risk really accelerates.

The knock-on effect: cross-contamination

A dishwasher that underperforms doesn’t just affect one plate.

Contamination can spread through:

Shared cutlery and cups

Serving utensils and jugs

Trays and reusable containers

Staff hands during unloading and stacking

Cloths used to “finish drying” items

Cooler cycles that leave items wet can actively encourage unsafe handling practices.

UK compliance: where assumptions become a liability

In the UK, food businesses and care providers are expected to operate safe systems, not hopeful ones.

While regulations don’t ban eco modes, Environmental Health Officers will expect you to demonstrate that:

Your warewashing process achieves effective cleaning and disinfection

Equipment is maintained and fit for purpose

Staff are trained and supervised

Risks to vulnerable service users have been assessed and controlled

If an outbreak occurs, “we were trying to save energy” is not a defensible position without evidence that hygiene standards were still being met.

Good practice for high-risk settings (care, health, education)

1. Use a risk-based cycle policy

Not all loads are equal.

Eco cycles may be acceptable for lightly soiled items, where validated

Standard or high-temperature cycles should be used for:

Heavily soiled items

Items exposed to high-risk foods

Services feeding vulnerable people

Document this in your food safety management system.

2. Make performance visible

Train staff to check:

Wash and rinse temperatures

Visual cleanliness

Odours or residue

Drying performance

In regulated environments, maintain appropriate records.

3. Maintain the machine aggressively

Eco mode cannot compensate for poor maintenance.

Clean filters and scrap trays daily (or per shift)

Descale regularly, especially in hard-water areas

Service chemical dosing systems

Act immediately on faults or alarms

4. Train staff properly

Most warewashing failures are human, not mechanical.

Focus on:

Correct loading

Avoiding over-stacking

Using the right racks

Keeping spray arms clear

Knowing when eco mode is not appropriate

5. Avoid false economies

If eco mode leads to rewashing, hand-washing, or towel-drying, you may be increasing:

Labour costs

Water use

Infection risk

while saving very little energy.

A safeguarding issue, not just an operational one

For organisations serving vulnerable people, dishwashing is part of duty of care.

Eco settings can still play a role—but only when:

The machine is designed for low-temperature hygiene

The cycle has been validated in real conditions

Staff are trained and supported

Hygiene is prioritised over headline savings

The business bottom line

Sustainability and safety are not opposites—but safety must always come first.

Eco dishwasher settings used without proper controls risk becoming a quiet weak point in infection prevention, particularly in care homes, hospitals, nurseries, and community food provision.

A genuinely responsible business saves energy without compromising hygiene, especially when the people affected may have no choice about where or what they eat.
