[NHCOLL-L:5951] Solvent to reverse archival microslide mountants

[Couteaufin at aol.com]

I have (in vain) been trying to find a less health-&-safety-sensitive  
subtitute for xylene to loosen coverslips on microslides where archival  
mountants such as Canada Balsam and Euparal have oxidised, become contaminated  or 
have otherwise darkened.  
I have had cumene suggested (but with no experience) as a possible safer  
subsitute.
Does anyone have any idea what I might be able to use please?
 
With all good  wishes, Simon
