Clean your iron with coarse salt

If your steam iron has black marks, and you want to clean it easily in order not to burn clothes, use an enough amount of coarse salt for the process.

Place a brown paper bag or newspaper on your ironing board and set your iron to the hottest setting. Start ironing the salty surface after sprinkling a substantial amount of salt over the paper bag or newspaper. Carry on in this manner until the salt removes all the marks.
