Any Ideas?
I had a fog light bust inside the lens, the second time by the way, now the inside lens cap is fogged and the silver part is black. The only thing that I can see is that the light just exploded. Its been 9 months now and the third light seems to be fine but now the light looks terrible. I removed the light assembly, and used a drinking glass sponge by putting it through the light hole but can't seem to clean it all the way. Does anybody have any ideas besides replacing it.

Is it maybe burned/melted or are you pretty sure it's just dirty? Maybe wrap a fairly stout pipe cleaner in a soft cloth?
Take it out and use some warm distilled water for the final rinse (distilled=little to no spotting). Throw it on the fridge afterward if you need to dry it fairly quickly, but let it warm back up inside the house if it's humid out.

are you running stock bulbs? Or something like the Silverstar bulbs? Just curious, I haven't heard of stock bulbs blowing that much, just the aftermarket bulbs.
You can look on ebay to see if you can find a new/used light assembly for cheap $$$.

I'm using the replacement stock bulbs. I thought of a possible short could be causing it to blow but after replacing it twice it hasn't blown since. I just can't seem to get rid of the black soot remaining on the silver miror part of the assembly. If I remove the lens cap it will probablecollect moisture.

FYI the cause for 99% of exploding halogen bulbs are residual stresses in the glass from the manufacturing process that we not annealed out. This was the number 1 customer complaint I used to deal with in my lighting engineer days.
Finger prints on the glass causes hot spots, which will shorten the life of a halogen lamp. Rarely will this cause the lamp to explode.
Best practice is to replace the whole assemby. Trying to get all the peices out is pointless.
Are you still under warranty?
