Should I wash my hands of this?
Has this expression ever been used as a way of suggesting a bribe?
The expression means to refuse to accept responsibility for; abandon or renounce.
It alludes to Pontius Pilate's washing his hands before having Jesus put to death, saying "I'm innocent of the blood of this just person" (Matthew 27:24).
"I've done all I can for him, and now I'm washing my hands of him.
And so, "Should I wash my hands of this?" simply means "Should I avoid ( or renounce) responsibility for this?"
