I agree with a previous reply to your problem. Try a different paraffin. In
my facility we do not use anything. We just put them back in the mold
warmer for the next day, cleaning the occasionally. Rarely do we have a
problem. You may want to try a different clearing reagent also. It could be
carrying over to much and softening your paraffin.
