Keith,
Depending on staining and/or crustation, I typically blast mine at 60-80 psi with very good results. Aluminum oxide also works well for aluminum but I protect the machined surfaces when using AO. I also lower the pressure a tad. Rick

If you don't have staining or oxidation to clean...try plastic to get back to close to original finish
