The plated parts, including the faceplate, and the finish on the back, should only be wiped over gently with a soft cloth. Never use isopropyl alcohol or any other chemicals or abrasive substances to clean these surfaces.
Submerge the heat sink, crucible, crucible lid, concentrate pad (if using), stem, and white sleeve in 91% isopropyl alcohol, for 10-15 minutes max.
Stealth Heat Sink
For the Stealth MV1, we recommend using an alcohol wipe or a q-tip. OK to soak but best not to.
Stealth Heat Sink Peeling
One thing we've noticed that causes this is soaking too long in isopropyl alcohol. 10-15 minutes is a sufficient amount of time. Another thing is when placed inside a cleaning receptacle along with other components, if swished around, objects are hitting the heat sink causing it to chip.
