need tool to clean up old AM STD seat

[Murphysf]

Hello

Looking for tool recommendations to clean up the seats on my AM STD shower valves. Please share any links from amazon or other.

I am a homeowner who has two sets of the american standard tract line (see attached) am looking for a tool to service the seats in my shower and bath tub.

Thank you.

The Seats are replaceable, and there are rebuild Kits available. You could use a seat resurfacing Tool.
