The Signature portafilter holder boasts a copper finish. In order to keep it looking its best, remove the brew head after use and wipe the area down with a clean cloth (using no chemicals or cleaners). Make sure all parts are dry before reinstalling to avoid a galvanic reaction. If coffee residue is left behind, the acidity can damage the finish overtime in the form of discoloration or corrosion.  The copper finish was changed in 2020 from a shiny plating to a matte, textured application: This increased its durability. If you have a "shiny" portafilter holder, and have noticed slight surface blemishing, we recommend use of [this metal polish](https://www.amazon.com/Eagle-One-Nevr-Dull-Wadding-Restoration/dp/B000CNBI1A/ref=asc_df_B000CNBI1A/?tag=hyprod-20&linkCode=df0&hvadid=167141040944&hvpos=&hvnetw=g&hvrand=14885669810173432574&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9033458&hvtargid=pla-275050101288&psc=1). It does a great job of removing surface discoloration that has not developed into a full-on chip.  If, however, your copper finish has tarnished beyond surface level, resulting in chipped/missing material, polish will not work.
