How can I effectively remove a white heat stain from wood?

To effectively remove a white heat stain from wood, you can try using a combination of baking soda and toothpaste. Mix equal parts of both ingredients to create a paste, then gently rub it onto the stain using a soft cloth. Let it sit for a few minutes before wiping it off with a clean, damp cloth. Repeat the process if necessary until the stain is removed.
