1. Place the frozen sponge in a sink or bowl filled with cold water. Make sure the water is not too warm, as this can cause the sponge to cook.
2. Let the sponge soak in the cold water for 5-10 minutes. This will help to loosen the ice crystals and make it easier to remove.
3. Gently rub the sponge with your fingers to help break up the ice. Be careful not to damage the sponge.
4. Once the ice has been removed, rinse the sponge with cold water to remove any remaining ice crystals.
5. Pat the sponge dry with a clean towel and allow it to air dry completely before using.
