Your iron stopped working because of the limescale? You can use natural remedies to descale your iron easy.
Limescale is an impediment for perfect ironing because it plugs those little holes in the soleplate. To get rid of this inconvenience, fill the iron with white vinegar and turn it to a high temperature with the steam setting on. Leave it on until all vinegar evaporates.
To clean the soleplate, prepare a paste with baking soda and white vinegar and dab a clean cloth into the paste and rub the soleplate gently.
