You're lucky that itīs leather and not a higher metal mail armor. There are a few ways to get rid of it. Spending a couple of turns at the entrance of the tower of eternal flames is one way (but slightly risky because you might be greeted by a strong monster). Showering under an acid trap can work, too.
Potions of exchange work as well, but it's a bit of a waste of the potion.
Oh and yeah, an unaligned altar could work too. Be sure to leave all other equipment behind, in case the angry deity will curse your stuff instead of dusting it.

You steal a scroll labelled HITME. The orc hits you.
