Good suggestion Togwt.
I'm giggling a bit because of a couple of things. The list of problems Plastik-Reiniger deals with should be amended to include dog saliva.
Years ago a buddy had a couple of St. Bernards. Great dogs, huge dogs. When he got dog slobber on his blue jeans it would take two washes to properly remove the stains.
So, I'm thinking you could modify the descriptor for 1z just a little bit to include: 'dog saliva, particularly St. Bernard dog slobber.'
Ok, ok, ok, I'm still giggling.
