Why your 'squeaky clean' hand-washed dishes might not be clean at all
Visually clean dishes don't guarantee actual cleanliness, as handwashing often fails to remove invisible residues and bacteria. Studies reveal that manual methods, limited by water temperature and soap chemistry, can even relocate contaminants. Dishwashers offer superior cleaning with higher temperatures and proper cycles, but filter maintenance is crucial for true sanitation.
