clean milk glasses

Milk tastes best when cold and from a glass.
Others like it hot and in a mug.

Anyway, when the glass is empty there's a haze in the glass of milk that sticks to the sides and bottom.

When you wash it with hot water it'll only get worse.

So put cold water in the glass and wash the glass with cold water.
When you feel the need to wash it with hot water, do it afterwards.

It's best to store glasses upside down to prevent dust coming in, but please clean the place where they have to stay first, otherwise storing glasses upside down will be a great way to infect yourself and the people around you.
