How McCafé Machines Are Supposed to Be Cleaned
According to McDonald’s operational standards (which vary slightly by country but follow similar principles), McCafé machines undergo multiple levels of cleaning:
Daily Cleaning
- Milk lines flushed and sanitized
- Brew units rinsed
- Drip trays cleaned
- Exterior wiped down
Automated Cleaning Cycles
Most McCafé machines are programmed to:
- Lock themselves until a cleaning cycle is completed
- Prompt employees to run cleaning routines
- Use manufacturer-approved cleaning solutions
Weekly and Deep Cleaning
- Brew groups removed and washed
- Internal parts cleaned manually
- Milk system disassembled and sanitized
In many locations, machines cannot function until cleaning is completed, reducing the likelihood of neglect.
Where Things Can Go Wrong
While systems exist, real-world conditions don’t always match ideal standards.
1. Human Error
Employees may be rushed, undertrained, or unfamiliar with the machine’s full cleaning process—especially in high-turnover environments.
2. Time Pressure
During peak hours, staff may delay cleaning cycles, even though machines often require them to operate fully.
3. Inconsistent Training
Not all franchises are equal. Some locations invest heavily in staff training; others struggle.
4. Milk System Complexity
Milk lines are the most sensitive part of any coffee machine. If not flushed correctly, residue can build up quickly.
These vulnerabilities don’t mean machines are “filthy,” but they do highlight where hygiene standards rely on proper execution.
