I am not advocated little glasses as the solution. I just would like to seen a poll to find out if hygiene is in fact the reason so many refuse the chalice when it is offered. And if it is, I would like to see any and all possible more hygienic solution explored.

That said, there are dishwashers available for the little glasses, and were this to become a catholic practice, it would now take long for some entrepreneur to manufacture one that washed many hundreds at once. The Lutherans, near me at least, consecrate the wine at the altar in a chalice, and then pour it into small glasses at communion. Chalices for this purpose have a small spout built into their top rims. Do you still object?

Unstarched purificators make it easier to wipe both the inside and outside of the chalice, which may increase hygiene. But since the organisms that spread infection are microscopic, there isn't a doctor anywhere who would describe better wiping as 100% hygienic. 

Besides, it all about perception.
