How often are people changing/rotating their paraffin? In other words the
dirtiest paraffin is how many days old?

This will depend on the amount of blocks processed.
I worked in places who used to change their VIP twice a week on Wednesday
Friday, and other that would change processor solutions once a week, but as a
rule, processor wax regardless of the make should ALWAYS be changed after a
maximum of 5
I have my processor set to notify me at 1500 blocks, at which time I
change the paraffins. I usually run 500 in the other solutions (same
notification system) before changing. It works for me!

I was instructed by a very knowledgeable person in the field that the
best processing for your tissue is to change it as often as you change
your clearant. So, if you change your clearant after 5 uses, you should
also change the parafffin after 5 uses too.
Hope this helped,
