Are you suggesting I might leave my horns in the dish rack, hope my wife doesn't notice, and cleans them as good as the plates? Seriously though, good advice about dishwashing liquids. Palmolive is the standard, though I think that Dawn (with a stronger degreasing) formula might be even better. One of the posters seemed concerned about the color of the dishwashing soap. I think that is a nonissue. Whatever they are using to color it isn't likely to even be detectable after dilution in water.
