Comment headway2 SNF 2004-11-18 14:25:26: 2 more small chucks

I normally clean the headway stainless steel and teflon chucks by 
soaking 10 minutes in acetone and 10 minutes in Isopropanol.  Then N2 
Blow dry.

However sometimes there is some traces of some polymer residue, 
presumably either polyimide or PMMA that has dried and cross linked.  
Can you recommend an alternative cleaning that could be performed?

Thank you,

James Conway
