Musty odour: a hygiene and perception problem

A musty or mouldy smell on freshly washed laundry is particularly damaging because it creates doubt about the establishment's hygiene. Users associate the odour with dirt and poor maintenance, harming the business's reputation.

Impacts

  • Perception of poor hygiene on the premises
  • Distrust in the cleanliness of the service
  • Negative reviews mentioning unpleasant smells
  • Customer attrition
  • Laundry that smells bad despite being freshly washed
  • Complaints and refund requests

Causes

Bacterial biofilm in the washer

Build-up of bacteria and mould in the drum, seals and pipework producing a musty smell.

Washers left closed

Doors closed between uses create a humid environment ideal for mould and bacteria.

Dirty or blocked filters

They accumulate organic debris that decomposes and gives off odour.

Detergent residue in the pipework

Accumulated detergent ferments and produces unpleasant smells.

Poor ventilation in the premises

Inadequate ventilation keeps humidity high, encouraging mould growth.

Solutions

Deep clean with Machine Clean

Empty cycles at 60–90 °C at least once a week.

Doors left ajar between uses

Instruct staff or users to ventilate the machines.

Clean filters and seals regularly

Weekly protocol to clean filters, seals and dispensers.

Use Oximatic + in cycles

Oxygen bleach that eliminates the bacteria responsible for the odour.

Biogold Q for prevention

Everyday detergent with built-in antibacterial action.

Preventive protocol

  • Run an empty Machine Clean cycle every Monday at 90 °C to remove biofilm

  • Include rubber-seal cleaning in the daily closing checklist
  • Verify the air extraction system is running and venting ambient humidity
  • Add Oximatic + to the standard programme as a permanent barrier against bacteria
  • Dismantle and wash dispensers every fortnight to prevent fermentation
