Foggy projector lens.No more..!!!!! Yeah!!!

Hi .
I searched the internet, regarding the issue on the bi xenon projector lens foggy . BMW e91 2007
and i didn't find anything useful , apart from "melting the headlight housing to get the front "glass" off.
My problem started when one of the xenon bulbs died. I ordered a new set from China ,Bad mistake..!!!! .Shortly after installing them , the protector lens began to get a foggy look instead of the clear glass it should have. In the end , the visibility at night was so bad that i have to do something..!!
As a new set of headlight costs around 2000 Pounds Sterling, I decided to have a go at them myself. I was sure the fog was on the inside of the lens, and i was 100% sure that I could get to it through the xenon dulp mount. No problem..!! sort of. By using a copper power wire 30 cm long and several pieces of polish cloth 10x10 cm and some clear wipex, wrapped around the wire and secured by some tape, I managed to completly clean the inside of the lens. By bending the wire to a L form I got past the high beam "shutter" inside the bulp housing that is blocking the lower half of the lens to be cleaned. I was very very careful when doing this.
Once the wire touched the glass I would hold it still and position myself so I could see the front of the headlight lens. Perfect!!!!
But to my surprise, most of the thick fog was on the outside of the lens , about 20% was on the inside and 80% on the outside of the lens - though still inside the headlight.
To get to the outside of the lens I went through a gap around the angle eyes with the same wire and repeated the cleaning process.
Anyway the final result was a full restoration,back to a 99% clear projector lens.
The reflector " arround the xenon bulp" got the same treatment.No damage to the reflector.!!!
Ps the only "damage" was the coating arround the lens. A touch was enough , even with water..!!! But nothing alarming.!!
Got myselfe a new set of real xenon bulps from Xenonkungen.com Powervision+60% 5000k D1S
A calibration of the light angle is neaded after this operation. hehe
The final preformance of the bi xenon is like new AWESOME...!!!!!

Hudmamma is back soon.!! Cya:thumbup
