I was surprised to see that anyone washed quilt fabric or quilts in hot water, but after reading all the posts it makes sense. The only thing I would hate is to have the fabric lose some of its luster and be dull from the hot water and the hot dryer. Would appreciate catching shrinkage up front.
I do know that since I got my new top loading high efficiency washer, if I don't use hot water and a double rinse on my towels they actually stink when they get wet by use. After much research on line, the consensus was that because the amount of water used has been cut back so much in these washers, that they don't effectively wash away all the detergent and grime residues. That would apply to dirty quilts as well. So probably should use hot water on the fabrics in the future.
