I agree with washing in cold on gentle and tumbling dry.. That's how I've always cleaned my cotton quilts. I use Dreft soap for this. The only caution I would give on having the tie quilt cleaned is be sure to take it to a cleaners you know. I have heard of such items disappearing. Is it really soiled or does it just need freshening? There are products to use in the dryer to "dryclean" items yourself.
