Cleaning & Care Instructions

First Use: Rinse with water or mild detergent before first use to remove surface dust. For baking applications, lightly coat the inside with butter.
Routine Cleaning: Soak in diluted detergent for 10–30 minutes after each use. Wipe clean with a soft cloth — never use abrasive scrubbers that could scratch the surface. Dry thoroughly and store in a box away from open air to prevent dust accumulation.
Oven Use: Place in the centre of the oven, maintaining ~10 cm clearance from the heating element and ~5 cm from oven walls.
Mold Seams: Some molds feature factory-cut seams to assist demolding. When pouring liquids, align the seams, then secure with plastic wrap or rubber bands to prevent leakage.
