Dear Prof. Knowles, I also believe trying out mechanical cleaning first and see if it does the job before considering any chemical treatment, as long as your sample material does not form an eutectic with the Pt strip. If you decide to clean the Pt strip, make sure to check that there's a minimal amount of height differences before and after treatment. This can verified by locating shifts in the Pt diffraction peaks.
