I'll bet it is your slides. Charged slides are a must. Also it would be
a good idea to keep a close eye on the temperature of the retrieval
solution. If the slides are actually boiling in the solution, it is too hot
and is unnecessarily agitating the slides. I would also caution against
using float bath adhesives being used in conjunction with charged slides.
The archives have countless explanations of why this goes wrong. Beyond
that I'd look into the processing of the specimen.
