No solution. Great problem though.
I presume that the Fiber Optic will not pass infrared; if it could you could just continue to use it. The "dirt" is probably black in the infrared region.
If it's absorbing at some wavelengths you could try blasting it with a high power laser. Either down the fiber or from inside the furnace. I presume that solution is to expensive though.
A possibility is to really make the end really (<1 micron) smooth so the dirt will not stick, or possibly coating the end with a noble metal (gold) less than .1 micron thick. That should pass the light and allow the dirt to be shake off.
These are not things I have done, or heard of though. Just things that come to mind.
