concrete residue on glass doors

[photogav]

While laying a concrete slab outside the contractor left some concrete splashes on our glass doors. The glass is specially tinted and so I was wondering if there was any products which would help me soften the concrete to help get it off.

Or would I be better trying to steam clean it off?

Thanks

Just use a sharp scraper, I wouldn't use a steamer for fear of cracking the glass.

I`d get onto the glass manufacturer first - go with their opinion
