I wash my glasses all the time with dish soap and have no problems with head retention or lacing. After drinking, I rise them with how water, scrub lightly inside & out with a sponge that dispenses Dawn dish detergent, then rinse again and dry immediately. Always have great head on my beers & good lacing. I've seen argument about dish soap on here several times, just don't think it holds up. There must be something else causing poor head retention.
