White vinegar, however, is a product that can be used to remove the cloudy look from your plastic drinking glasses. Pour 1 cup of distilled white vinegar into a container. Place one cloth into the container so that the entire cloth is saturated by the distilled white vinegar. Stuff the wet cloth into the plastic glass. 3 Ways to Clean Foggy Plastic - wikiHowhttps://www.wikihow.com/Clean-Foggy-Plastic- https://www.wikihow.com/Clean-Foggy-Plastic+&cd=12&hl=en&ct=clnk&gl=us" rel="nofollow noopener" target="_blank">Cached

Nov 13, 2017 - How to Clean Cloudy Glass and Prevent Future Buildup ... minerals, all you have to do is soak your cups for five minutes in white vinegar.I would try the vinegar, cheap for sure, but will tell you if they are going to clear up or not.
I have worked in art class for over 30 years. For tough stains vinager is wonderful. However, when that does not work:
1) check to make sure it is glass not plexiglass. (Plexiglass gets permanent fog if any clearner used contains ammonia)
2) hard water fogged glass in a small area try these:
A) nail polish remover (with acetone)
B) tablet with water denture cleaner ( great for tea or hard water stains on glass or china wear also)
C) diluted lime away (make sure to use rubber gloves)
CLR should clean them right up.
Usually once they are foggy, they stay foggy. I've even tried the cleaner meant to make headlights clear again. Didn't work
I would use CLR.
To help remove this and bring back the clarity of your cups use household bleach. Fill a bowl of warm water and add a dash of bleach. Soak the plastics in the solution, and wash thoroughly afterwards.
