Cutters should be hand washed after every use with warm soapy water (not hot), with a mild dish soap and rinsed thoroughly.
Do not soak cookie cutters in water for extended periods.
Never put cookie cutters in the dishwasher, as the high heat and harsh detergents can damage them.
Immediately dry the cutters with a soft cloth or towel after washing to warping. As an option, a salad spinner can be helpful for rinsing and drying cookie cutters, especially those with intricate designs.
