After using a 3D-printed cookie cutter, wash it promptly with warm, soapy water. Use a brush to scrub all surfaces, paying special attention to crevices where bacteria may reside. Prompt cleaning prevents food particles from drying and becoming more difficult to remove.

After washing with warm, soapy water, rinse the cookie cutter thoroughly and allow it to air dry completely. Proper drying helps prevent moisture buildup, which can encourage bacterial growth. Optionally, you can sanitize it with food-safe solutions such as white vinegar (diluted 1:1 with water) to further minimize bacteria.

Do not place 3D-printed cookie cutters in dishwashers or expose them to high temperatures, as the heat can deform the plastic and compromise the tool’s integrity.
