Or someone should tell window manufacturers Dawn isn’t approved for cleaning windows by it manufacturer. 
Why does it need to be approved by P&G?
Weren’t we talking about what manufacturers we approving or not approving? If so, then P&G’s approval is pertinent, eh?
Even if the window manufacturer approves it? Isn’t that what ultimately matters in terms of the sticker? Has there ever been a case where a WC’er has been held liable for using Dawn on a window with the sticker?
My post actually was in regard to the concept of worrying about what any manufacturer says is acceptable or not. The sticker is as worthless as the paper it’s printed on in my opinion, so I was enjoying the humor of the concept.
