A sign of a "beer clean" glass is when water sheets and runs off rather than forming drips. This characteristic indicates that the surface of the glass is free of any residues or film that could interfere with the formation of foam and affect the overall drinking experience. A glass that has been properly cleaned will typically have a smooth, clean surface that allows water to flow evenly, promoting better carbonation and head retention when beer is poured.

In contrast, if water forms drips, it suggests that there may be some oils or other residues present, which can inhibit the ideal presentation and enjoyment of the beer. A glass being free of any markings is indeed a positive aspect but does not directly relate to its ability to interact with beer properly. Similarly, while having no residual odors is important for maintaining the integrity of the beer flavor, it does not directly indicate the glass's cleanliness in relation to how beer is served and presented.
