Deletion of Stain removal

Comment: CSD 11 only refers to pages that originally are written to exclusively promote a specific entity or product. Here, http://en.wikipedia.org/w/index.php?title=Stain_removal&oldid=204283409 the very first version of this article looks more like a general essay on various alternative ways to remove hair stains instead of using hair dye. How did this page get named "Stain removal" anyway? And how did it evolve into promoting various products? This page |needs an extreme makeover or merge, not deletion

Comment: The nomination utterly fails our |editing and |deletion policies.  Stain removal is a massive topic with an interesting history and deletion would do nothing to improve our coverage of it

Comment: to Stain#Removal per User:LinguistAtLarge, because this is a useful search term; but if any of the current article content gets merged anywhere, it should go to Hair coloring, not Stain, because it's all a detailed analysis of hair dye stains, not stain removal in general; adding the material to Stain would unbalance that article.  Anyone merging material from this article should be careful not to include material that could be construed as advertising for "Repelle Hair Color Stain Shield Wand".  Just in case anybody is inclined to vote "keep", note this article is both an #OR|essay and an |advertisement for the aforementioned product
