I work in a yacht club and on an average evening I probably have to put about 1000 glasses through the machine, my idea is as follows:
Wine glasses with a special coating, which is completely water resistant. Water would just roll straight off of it leaving no trace of its content. Like the water off a ducks back, leaving it completely dry.
This would greatly speed up the cleaning and drying process, currently you have to wipe over every single glass getting rid of all the water. But if the water rolled straight off that's half the job done.
I have not looked into the health and safety side, but I'm sure there's a non-harmful coating that could be used.
Unless you do the work I do you could not understand how helpful this would be.
