Where the “Dirty Secret” Rumor Comes From
The idea that McCafé machines are “dirty” didn’t come from nowhere. It stems from several overlapping issues:
1. Viral Social Media Claims
Videos from self-identified former employees sometimes claim machines weren’t cleaned properly or that cleaning cycles were skipped during busy shifts.
2. Confusion With Ice Cream Machine Failures
McDonald’s ice cream machines have famously been the subject of breakdowns and sanitation issues. Many people mistakenly assume coffee machines face the same problems.
3. Lack of Visibility
Customers never see the cleaning process. When you can’t see something, suspicion fills the gap.
4. High Volume Usage
A machine that serves hundreds of drinks daily naturally raises questions about residue buildup, milk lines, and internal hygiene.
But suspicion alone doesn’t equal fact.
