Just curious - what is Weck soap?

Wendy, 
 
sounds like they were not processed correctlly, not sealed, or both. You can
melt them down, go back through xylene 2 to 3 changes for 2 hours each, then go
back to 100% alcohol for 2 to 3 changes for 2 hours each, then reprocess back
to paraffin.
 
FYI: Museums use a method of boiling in Weck soap to bring back mummy tissue.
Had to use that method once when a tech left fresh breast sections on the xray
tray overnight.
