Hi blokes, I know I asked this question about a year ago but I can't find it and my headlights are like candles in the wind...lol

I have sealed HID lights and after too many deep bog holes they eventually filled up with muddy water and stained everything inside, hence the reflectivity is quite poor.

Being a sealed unit I can only get the globe out and the hole is only a 20 cent piece in diameter to get inside so hard to get something inside and then bend around to scrap the stains off the back.

How does everyone else get the mud stain off??????????

Pipe cleaner that you bend around maybe and scrape the crap off??

I have tried sitting all kinds of chemicals in there, swirling around and let sit for hours but no joy!
