Montag instructs Faber to burn in the incinerator everything that he (Montag) has touched and then rub everything else down with alcohol.
Faced with the threat of another mechanical hound pursuing him, Montag takes precautions to evade capture. He changes his scent using a scent-destroying powder and travels through the river to mask his trail.
So, Desperate for guidance, he instructs Faber, his mentor, to remove any identifying marks, fingerprints, and the scent of his presence from the house. Montag urges Faber to clear any evidence linking him to books or rebellious activities. This strategic move reflects Montag's determination to survive in a dystopian society where intellectual freedom is suppressed.
