Bernd, the wisdom has always been 'never use a wet means of cleaning the screen'... to late, never mind. You say the mirror box foam is rotting, this means the light trapping around the back is probably turning to goo.
Don't make matters worse, I suggest. Take the camera to a good technician and have them clean the screen (they've probably rectified peoples bodges a thousand times and know just what to do) replace all the foams and CLA it for good measure. Job Done.
