Answer: Assalamu alaikum wa rahmatullah,
No, if a person dies in a state of ritual impurity (janaba), they do not need to be washed and bathed twice because they are no longer morally responsible so there is no need to lift that state. And in any case, if somebody requires a ritual bath (ghusl) due to two separate causes, one bath is sufficient to lift their state of major ritual impurity.
As for washing the mouth and nose of the person who dies in a sate of major ritual impurity, it is a position chosen by Imam Shurunbulali (Allah Most High have mercy on him) in his Imdad al-Fattah and elsewhere. However, both Tahtawi and Ibn ‘Abidin note that this is not the relied upon position of the Hanafi school.
Khayr al-Din al-Ramli writes in his gloss of al-Bahr al-Ra’iq, “The unconditioned nature of this ruling found in the primers (mutun), commentaries (shuruh) and legal-edict (fatawa) works [namely, that the mouth and nose do not require washing] entails the inclusion of the one who died in a state of major ritual impurity.”
[Shurunbulali, Maraqi al-Falah with Tahtawi’s Gloss; Abu al-Su‘ud, Fath al-Mu‘in ‘ala Mulla Miskin; Ibn ‘Abidin, Radd al-Muhtar ‘ala al-Durr al-Mukhtar]
