Adishcloth, dishrag,[1] or in British English, a tea towel,[2] is used in the kitchen to clean or dry dishes and surfaces. Dishcloths are typically made of cotton or other fibres, such as microfiber.
Dishcloths are often left damp and provide a breeding ground for bacteria. Since the kitchen sink is used to clean food, dishcloths are routinely infected with E. coli and salmonella. In 2007, a study from the Journal of Environmental Health found that putting a damp dishcloth (or sponge) in the microwave for 2 minutes killed 99% of living pathogens.[3] However, fire departments have subsequently warned people not to do this as it can be a fire hazard, especially if the dishcloth or sponge is not sufficiently wet. Several small fires have been started as a result of people following the advice from the study.
