Hi Dorothy,

Depending on the brand,  some processors will heat the preheat the
retort.  Then pump it back into the last paraffin.  The VIP does this,
which is what I have.  I clean my molds this way, once a week maximum,
and have not had problems.  I had an old MVP prior to the VIP and it did
not pump back any molten paraffin.

At the previous facility I worked at, we daily cleaned our mold in the
cleaning cycle until we had a problem with the processor and was told
the field service engineer and then the company that doing this was
on the machine with all of the excess paraffin in the tubing.  I do
know if that has any merit, but, we quit doing that and never had that
type of problem again.  Just a thought!!
