How to Clean a Stoneware Cookie Jar Without Damaging It

Quick answer

Hand-wash your stoneware cookie jar with mild dish soap, warm water, and a soft sponge. Never soak it or put it in the dishwasher, and always dry it completely before replacing the lid.

Step-by-step cleaning guide

1. Empty and dust the jar: Remove all cookies and crumbs. Use a dry pastry brush or a soft cloth to wipe away loose dust from inside and outside. This prevents gritty particles from scratching the glaze during washing. Check the lid fit—crumbs can prevent a tight seal.
2. Wash with warm, soapy water: Fill your sink with warm water (not hot) and a few drops of mild dish soap. Dip a soft sponge or microfiber cloth, wring it out, and gently wipe the jar inside and out. For stuck-on residue, let the soapy water sit for 5 minutes before wiping—never scrub hard. Avoid soaking the jar; standing water can seep into unglazed areas and cause mold.
3. Rinse and dry immediately: Rinse with cool or lukewarm water, tilting the jar to let water run out. Pat dry with a lint-free towel, then air-dry upside down on a towel for at least an hour before replacing the lid. This prevents trapped moisture that can lead to stale odors or mildew. If you see water beads inside after drying, the jar isn’t fully dry—wait longer.
