How can I effectively remove a heat mark from a wood table?

To effectively remove a heat mark from a wood table, try placing a cloth over the mark and using a warm iron to gently heat the area. This may help the wood fibers to expand and release the mark. Alternatively, you can try using a mixture of equal parts vinegar and olive oil to gently rub the mark until it fades. Remember to test any method on a small, inconspicuous area first to ensure it does not damage the wood.
