How do you get heat marks off Basalt?

I dont have personal experience on this but I can suggest a few methods: 1. Try using a soft cloth and rubbing the heat mark with toothpaste or baking soda mixed with water until it disappears. 2. Heat up the marked area with a hairdryer until it becomes warm but not hot, then apply a layer of mayonnaise or vegetable oil over the affected area. Leave it for 30 minutes, wipe it clean and repeat until the mark disappears. 3. Rub the area with a damp sponge dipped in vinegar or lemon juice, then rinse it off. Its important to note that basalt, like any natural stone, is delicate and can be easily scratched or damaged, so its best to avoid harsh chemicals or abrasive materials.
