Dirty inside window glass....

This is not a great picture, but how do I clean dirt/spots between the third brake light and inside rear window glass.... driving me crazy....

 

Pop off the light housing and wipe it

 

When the high mount brake light is near / at the rear roof line, for the TL guys it may be relatively easy:





However, for the TSX and CL-S model folks, where the high mount brake light lives near / within the rear shelf, usually the rear shelf has to be removed first then one can get at the brake light itself for removal & subsequent glass cleaning.

CL-S:
