Cleaning dishes and kitchen surfaces after a disaster

Thursday, May 14, 2015

Depending on the source, floodwaters could contain anything from germs, debris, toxic chemicals or hazardous materials to pesticides, gasoline or other household chemicals. That is why in the aftermath of a flood, kitchen equipment and surfaces require special attention.

“For your safety and the safety of your family, it’s important to thoroughly clean, or in some cases throw away, kitchen items and equipment exposed to floodwaters,” said Gina Peek, Oklahoma State University Cooperative Extension housing and consumer specialist.

Before tackling the task of cleaning and disinfecting your kitchen, be sure to put on gloves and other protective clothing to prevent skin contact, irritation or infection.

“Throw away wooden and plastic dishes and utensils as well as baby bottle nipples and pacifiers that have come into contact with floodwater because these items cannot be safely cleaned,” Peek said.

Meanwhile, metal pans, ceramic dishes and utensils, including can openers, can be cleaned with soap and hot water. These items should be rinsed then sanitized by boiling in clean water or by immersing for 15 minutes in a solution of 1 tablespoon of unscented liquid chlorine bleach per gallon of clean water.

“If the dishwasher is operational, run three complete cycles while it is empty to completely flush the water lines before washing any dishes or utensils in it,” Peek said. “Be sure to clean cracks, crevices, handles and door seals of the dishwasher, and all other kitchen appliances.”

Also, carefully sanitize countertops with soap and hot water. After rinsing the surface, apply a solution of 1 tablespoon of unscented liquid chlorine bleach per 1 gallon of drinking water (or cleanest, clearest water available) and allow the surface to air dry.
