Tips for stains
Never put a garment away with spills or stains on it. The warmth of a closet and exposure to natural or artificial light and to the atmosphere can contribute to setting a stain.
Bring in a stained garment as soon as possible, preferably within a few days, to prevent the stain from setting.
Do not iron stained or soiled clothes; this will set stains and drive the soil deeper into the fabric. Always have soiled clothes cleaned or washed before ironing.
Do not attempt home spot removal with either water or a cleaning fluid without testing first for color fastness Wet an unexposed area, such as an inside seam, and blot with a clean cotton towel or gauze to make sure the color is fast.
Never rub a stain, especially when attempting to remove a stain from silk. Blot the stained area with an absorbent dry cloth underneath. This will help remove the staining substance without spreading the stain and will avoid damaging the fabric.
