Can undo the effects of time and wear, returning an item to the state it was in at an earlier point in its life's journey.

Good for:
- Saving money on laundry.
- Never having to polish metal.
- Fixing scratching posts that have been shredded by tiny sharp claws.
- Helping beloved shoes go back to their 'fresh from the factory' state.

Bad for:
- Living things (too complicated).
- Things that are too big (gotta be reasonable 'you could carry it' size).
