The first thing you'll see me do with many of the smaller metal parts that are full of gunk, is I'll put some simple green in a stainless steel cup and set that on some heat, in my case, I have an electric stove in the garage I use for powder coating. So I took apart both of the mechanisms and put all the metal parts in some boiling simple green, this really helps break down the grease and oil. After about 20 minutes most of the grease had fallen off, I got the remaining crud off with a brush.
The picture above is one of the parts about 10 minutes and grease that is on the surface can be easily wiped off though I would since you'll burn the flesh off your skin.
Once they were cooled down I did a once over with a wire brush to knock off the loose oxidation from the surface, then I powder coated them gloss black. I'll eventually do a write-up about my powder-coating set up and a how-to. As for the final product, they came out alright, depending on how they look in the engine bay. I might just get an OEM zinc plate set, but for now they are great, considering what I started with!
