You know that bloom that appears on glasses after a few months of dishwashing?
I’ve seen various suggested remedies to remove this, but so far none has worked for me. Once the glass is spoiled, you have no choice but to either put up with it or bin it.
So always wash any more precious glasses by hand.
Over the past year or so, though, I have found that placing my everyday glasses on the upper shelf of the machine has kept them lovely and clear.
