The filter can isn't as bad as it looks.  Two screws on top come out from the top of the chassis on each mounting tab and the can will lift away from the chassis.  You can then clip the feed wires and remove the can completely.  With mine I propped the can up by the mounting tabs over a metal coffee can.  I then placed it about a foot in front of my 35000 btu garage torpedo heater.  After about 5 minutes the tar softened and slid right out of the can into the coffee can.  A good heat gun could probably do the job, just take a little longer.  DO NOT DO THIS IN THE HOUSE IN YOUR OVEN!!!  The fumes produced will stay with you for some time to come.  Definitely an outdoor project.  Also, order a copy of the schematic from Chuck Schwark .  Well worth the cost with all the information he provides with his packet.  Take care, Gary
