I removed the brass from the door. soaked them in lacquer thinner to remove the several layers of paint. Wiped off the excess paint and then used a medium coarse steel wool on the brass. After that I put a generous coat of brass refurbisher on the hardware. Wait 5 minutes and wipe off. Then buff to a shine with a clean soft cloth. After that lightly spray with a brass protector to prevent tarnish. It really worked great.
