Plumber I know said that powder laundry soap will clog pipe quicker the liquid, same thing with dish washers. I prefer to call them dish dryer as I have always preached before loading. I do remember as an apprentice meat cutter wear my Chuck Taylor All Stars at work they would get really funky from the blood. I alway washed them in the dish washer of the apartment I lived in, with very good results.Ok, I had time to burn, I watched the whole thing. Now I'm convinced we made a mistake by going to gel packs thinking they were cheaper / better. If we can use less soap and get a better wash, even better. Might even look at going back to powdered laundry soap. My wife loves the pod soap there - but she'll throw 2 or 3 frickin pods in with a towel load, I don't get it. That stuff is more concentrated than powder, and we have a "high efficiency" machine so you're not supposed to use a lot of soap anyway.
