If you need to iron a silk item, set the iron to delicate and use a very gentle hand, too much heat will easily scorch the fibers.
If some salad dressing dripped onto a silk tie, sprinkle baking soda over the entire area and let it sit for five minutes or so.
The powder will absorb the grease from the tie without damaging the fabric.
If any trace amounts remain, dip a white cloth into some white vinegar and ring it out well, then gently dab the stain to break up the grease. Let the vinegar dry, don't rinse it out.
Stain on a silk blouse? Add a teaspoon of gentle baby shampoo to a basin of cool water and completely submerge the garment.
Swish it around and gently rub the stain to be sure the solution is getting to the problem area. Let it sit for five minutes.
Empty the basin and refill with cool water. Submerge the item completely to rinse all of the soap away and then gently roll it in a soft towel to remove excess moisture, don't ring it out, you could damage the item. Hang it to dry.
I hope these simple steps help save your silk items and save you from a large cleaning bill! i'm Mrs. Fixit and it's just that simple!
