Stephen Koob, the head of the Museum's Conservation Department from 1998-2020 writes: 

Cleaning your beloved Pyrex — whether clear, colored, decorated, or plain — can be a challenge and should be done with care.

First, never, ever put any Pyrex through a dishwasher. This is the fastest and most damaging thing that you can do. It will slowly etch the Pyrex, and probably will not even do a decent job cleaning it. I generally recommend that you never put any glass through a dishwasher.

Check out his blog post "How to Clean Pyrex," for more information on tackling stubborn grease stains.

Please do not hesitate to ask us your glass-related questions in the future!
