Etching platinum with Multi
How to etch platinum with Multi-Etch
|Although Multi-Etch will not etch platinum, it can be used to remove all steel ions prior to welding or soldering. Rather than using the standard protocols involving a 15-minute dip in nitric acid, a 15-second dip in Multi-Etch is just as effective.|
|Process||Etch time||Surface change|
|135°F regular strength||15 seconds||None|
|Note: 3 minutes will remove enough to be picked out; etch longer to dissolve whole bit.|
|Process||Etch time (minutes)||Surface change|
