Question:
I have a keyboard that probably has some sort of chametz stuck under the keys. Should I buy a new one for Pesach?
Answer:
You do not have to buy new one for Pesach, try to clean the keyboard of any visible chometz, and you do not have to worry about a few crumbs that might have fallen inside the keyboard. This is because it is only a minute amount, and you are not going to come to eat.
