"However, does anyone remember the cut glass/crystal? glasses that used to be given away with tokens when you bought petrol? As DH was travelling quite a lot then, we have quite a collection.
I thought recently - why keep them in a cabinet? Just use them!
They then go in the dishwasher and seem fine so far."
You say "recently".
A warning: About 5 years or so ago I started putting my "free-with-petrol" glasses in the dishwasher as it seemed a pity not to use them. Unfortunately, they've just started the clouding process. We don't use the dishwasher every day which might be why they've taken a while to start clouding, but I'm quite upset that I didn't give it a thought until too late!! I've been trying Bar Keepers Friend, vinegar, and a paste of the two. There might be a slight improvement, but I can't be sure!
