Crystal glasses often becomes cloudy as a result of heat from the dishwasher combined with lime, calcium, or rust in the dishwasher water.
This dirty concoction of minerals effectively bakes into the glass's pores, creating the cloudy or foggy appearance. Although this is common, it doesn't have to be permanent.
Here's how to get it clear again. Before cleaning, however, be sure to remove your rings and turn the faucet aside to avoid chips.
Apply a soft-scrub cleaner onto a clean-lint-free cloth, and apply it to the inside of the glass.
Let this solution sit and work its magic on the glass for several hours. The cleanser needs time to do its work before you finish yours.
Rinse the glasses thoroughly under cool, running water. Buff dry with a clean, lint-free cloth.
If it's still cloudy, get an inexpensive commercial calcium, lime and rust cleaner.
Pour the calcium, lime and rust cleaner into your cloudy glass - full strength. Allow the cleaner to do its work for at least several hours or as long as overnight.
Rinse the cleaner thoroughly, again with cool water, and dry using a lint-free cloth.
