If ever you have a burn you should immerse it in water for 10 - 20 minutes minimum as soon as you can(i.e. immediately). If it is very bad then get to a doctor or hospital quickly. If you put foreign substances on the burn it can sometimes be counter - productive as you have to go through the pain of having it removed before they can put the correct stuff on it.Water is the best to re-hydrate and stop the damage - don't put butter or sauces on it.
