What measures does Sikes take in order to rid himself of evidence(or guilt) of his murdering Nancy？

After sitting completely still, staring at Nancy’s body, Sikes finally gets up and cleans himself, his clothes, and his weapon off as best he can. He leaves the apartment with his dog, and locks the door behind him. He wanders around, stopping for a bit to sleep, then wanders some more. Finally, by night, he finds a pub remote enough that he feels comfortable entering, and goes in for dinner. While he is eating, a peddler comes in who is selling stain remover. To encourage buyers, he says that he will get the stain out of Sikes’s hat, and grabs it. Sikes lunges for it, and upon getting back, rushes out of the pub.
