Wikipedia:Articles for deletion/Stain
as an article about unintentional discoloration of surfaces or materials by exposure to colorants or chemicals.  There is an article Wood stain about stains intentionally applied to wood, and there is an article about Staining used in bio labs, like Gram staining , which by-the-way has a thorough "how-to" section, and which needs it, to explain what gram staining is. An article on unintentional stains suggests a section on stain removal, which runs the risk of being the dreaded "how-to" of useful information which Wikipedia  forbids for some reason.  Hundreds of books exist about stains and their removal http://books.google.com/books?as_q=&num=10&btnG=Google+Search&as_epq=stain+removal&as_oq=&as_eq=&as_brr=0&lr=&as_vt=&as_auth=&as_pub=&as_sub=&as_drrb=c&as_miny=&as_maxy=&as_isbn= , and hundreds more books discuss particular types of unintentional stains http://books.google.com/books?lr=&as_brr=0&q=%22semen+stain%22&btnG=Search+Books ,  http://books.google.com/books?lr=&as_brr=0&q=%22blood+stain%22&btnG=Search+Books , satisfying |notability
