Applying itr and camphor to the deceased

Q:

1. After giving the mayyit ghusl, it is reported in the hadith that itr should be applied to the head and beard, and camphor should be applied to the places of sajdah. In place of camphor, is it permissible to apply itr as we see some people nowadays applying itr?

2. We notice some people when applying itr to the knees of the mayyit, expose his knees and some even touch the knees with bare hands, is this correct?
