Measures - 5 3/4" Tall 2 3/4" across Rim 2 5/8" at Base

In Great Condition - No chips, cracks, or repairs

Look at last 3 photos for more condition not sure what it could be on 1 of the glasses

Please let me know what you think I can use on the glass for the white stuff I already used dish soap

My guess its either water staining or age
