Dear Rabbi Simon,
My grandmother has moved out of her home and has glass/crystal glasses and decanters that we can take or give to a charity shop. Kashrus was not observed in her home.
Can you please advise if we can use them?
Thanks,
Crystal
Dear Crystal,
You may use these glass and crystal items without cavil. As a matter of extra certainty, you can apply the process known as מלוי ועירוי (literally, filling and emptying). Fill a bathtub with water and submerge the items for 24 hours. Empty the water and repeat the exercise twice. Then you’re done. Lechaim.
Best wishes
Rabbi Rashi Simon
