Test your beer glasses



  • A simple and effective way of testing your glasses for cleanliness is easy to do.
  • Take a glass from the shelf and fill it with cold water.
  • Dry the outside of the glass.
  • Drain the glass over a sink.
  • With the glass held upside down check to see if the remaining water breaks into beads or droplets. If so this might indicate that your glasses are contaminated with grease or detergent residue.
  • If the remaining water drains away in one continuous sheet or film then your glass is probably clean.
