The Best Way To Clean Strawberries So They Remain Fresh
Knowing how to properly wash and store strawberries is imperative to their freshness. To achieve this, all you’ll need is hot water, a dish towel, and a breathable container.
A food reporter for The New York Times found that if you submerge strawberries in water that is 125 degrees Fahrenheit for 30 seconds, it cleans them and prolongs their life.
At this temperature, the water isn't so hot that it damages a strawberry, but it is hot enough that mold will either be reduced or eliminated. It also prevents mold from spreading.
You will still need to thoroughly dry them using a kitchen or paper towel before placing them into a breathable container. Your strawberries should last for up to a week.
