Have you ever tried Dryel...oh I love that stuff. It is the at-home dry cleaning kit you can buy at the grocery store. I just discovered it about a month ago. I was brave enough to give it a try on some new sweaters I got that needed to be drycleaned but I didn't have time to take them to the cleaners. The starter kit comes with a big bag. You place the article to be washed inside the bag along with a Dryel sheet (sort of like a wet nap). You put it in the dryer on low heat. It really works! I've washed sweaters, scarves and pillows. You can wash items that you are not sure about...even it it has been machined washed before. Dryel will take care of most delicates.
Wellllll if it were me.... I would wash it regular cycle AND hope for the best!! But thats just me....
