Zevahim 88: New Clothes, Blood, and No Dry Cleaning

Items are sanctified when they are put in holy vessels, but not all substances in all materials of vessels. So too, the priestly garments also atone. Note that the service needed to be done in new, pre-washed garments, for the sake of the glory (and wealth) of the Temple. Also, how the priestly garments are connected to the sacrifices from the Torah. And a quick catalogue of which garment atones for what sin. Plus, bloodshed and evil speech (lashon hara) seem to have two ways to atone (each), and also are named as acts for which there is no atonement.
