I guess I am in the minority. Dry iron only...water can rot out the insides of the iron (that's why they leak often) especially if you use tap water or highly mineralized water (learned this from a long time tailor). I don't use starch because starch can attract bugs (moths and carpet beetles) which can damage fabrics on stored quilts. (If you wash the quilt when it is finished, you do remove the starch, but then how do you get the crisp look back without starch?) This is just my opinion...
