I also wash my quilts afterwards for many of the same reasons stated here. Even though I don't like a crinkly look on myself I love the crinkly look on them but also because of possible allergies and possible dye runs but I like to give my quilts a good head start depending on where they are going to find a home. I also think that it makes the quilts softer and more cuddly. I use quilt wash that I found at JoAnns and bought on sale for 50% off and I had additional discounts on top of that. It is fragrance free dye free and concentrated. It comes with a spoon for measuring out and it only takes like 1/2 teaspoon for a full load of quilts. The jar was originally $10.00 I think I ended up paying around $4.50 plus tax, and I have washed close to a ton of quilts and fabrics with it and it is still over half full.
