Question
I was told that after using my own kli (bottle or cup) to wash hands after the cemetery that it could not be used again for drinking etc. Is this true?
Answer
This is not true. The Pitchei Teshuva writes that one should wash ones hands after the cemetery before one enters a house. If one has reached ones house - someone else should bring out a dish for one to wash outside.
