I have some salvaged bosch rexroth t slot extrusions and brackets that I will be using for a CNC router project. The extrusions are in great shape. the t-bolts and other hardware is rusty, which I am treating with Evaporust and Caswell black oxide which looks great.
Some of the brackets are covered with whitish corrosion. What is the best way to clean the brackets up and make them look nice? I don't know if they are pot metal or aluminum.
The router will be a mix of steel (painted) and the aluminum extrusions with profile rails.
