I bought a case of Sprayway Glass Cleaner after a few on this forum recommended it and I used it to clean the glass in the car both inside and out and I realized that the pano roof is looking a bit dull from all the salt they've been using lately. Is the top of the pano roof actually all glass? As in "glass glass?" Just wanted to check before I start to regularly use Sprayway Glass Cleaner to clean the entire pano roof which encompasses the entire roof structure of the car.

For the small areas I tested it, a glass cleaner really seams to completely clean and pano roof and make it shine -- much better than what it looks after it comes out of the car wash.

Thanks for any recommendations or suggestions on keeping the pano roof clean -- and sparkling

From Daimler themselves:

Cleaning the panorama roof with power
tilt/sliding panel (sedan)
X Use a soft, clean cloth and a mild window
cleaning solution.
An automotive glass cleaner is
recommended.
! Do not use a dry cloth, abrasives, solvents
or cleaners containing solvents. Doing so
may damage the tilt/sliding panel.

That makes sense. Thanks!

I think on the W211 the front panel is glass and the rear panel is some kind of composite.

Are you sure? It all seems like glass to me.

It's all glass. I think MB says not to use solvents because they don't want the residue to junk up the rails in case it falls in the cracks.

I'm pretty sure, I will see if I can find some documentation. But even if you knock on the rear panel, it has a different feel and sound which to me didn't feel like glass. Also, the warning sticker about cleaning was only on the rear panel in the W211. On my W212, I believe both panels are glass and there are no warning stickers on either.

That's exactly right. If people would read carefully you'll see that they say: using solvent may damage the tilt/sliding panel. I pulled that section I posted above directly from MB.

Both panels are glass on the W211. A guy on another MB forum posted about buying a salvaged W211 that was in a hail storm. Both panels were blown out identically, and both were glass.

Any sound difference (when tapping on it) is because the rear panel doesn't sit in the same frame (the front is in a sliding mechanized frame.)

WEBSRFR: Stoner's Invisible Glass or the Sprayway you have works great, no problems there.
