What Is a GlassWasher?
Glastender, Inc. invented the world’s first automatic rotary glasswasher in 1969. Today, Glastender glasswashers
have been installed around the world. But what is a glasswasher? It is simply a piece of machinery that washes
glassware, which eliminates the need for human labor and the conventional three-compartment sink. The glasswasher is, in effect, a mechanized three-compartment sink. It “washes”, “rinses”, and “sanitizes” glassware.

Please read on to learn more about this simple machine.
Hot water and a preset portion of detergent join in the tank. During operation, hot soapy water is
pumped in a forceful, but gentle, spray pattern across the moving glassware. When the wash cycle
is complete, all water is drained. While the drain is still open, clean water pre-rinses the holding
tank to prepare for the rinse and sanitize cycle.
Fresh water and a preset portion of sanitizer and rinse aid join in the tank. During operation, rinse
water is pumped in a forceful, but gentle, spray pattern across the moving glassware. At the end
of the cycle, all water is drained so the next load can begin with fresh, clean water.
