IRON TROUBLESHOOTING
Never iron areas with traces of perspiration or other marks: the heat of the plate
will make the stain “stick” to the fabric, making them irremovable.
To avoid leaving a burn mark on silk, woolen or synthetic garments, iron them
inside out.
Velvet garments can be handled by ironing in one direction (following the fiber).
Do not press down on the Steam Iron.
It is easier to iron fabrics if they are not completely dry. For example, silk should
always be ironed damp.
