I even use the blue Dawn for handwashing quilts in the bathtub. I line the tub with a sheet, place the quilt on it, then fill the tub with warm water. I add the blue Dawn and "swish" everything around until I think the quilt has been cleaned enough. I drain the tub and repeat the "swishing" process several times with clean water and squeeze out as much water as I can by rolling the quilt inside the sheet. I let quilt air dry on the back porch at my daughter's house. I like the fresh smell, and it's much easier on the quilt than agitating it in the washing machine.
