beer contains enzymes for the fermentation process so to remove these efficiently you will need a biological cleaner
I suggest that you get a professional valeter on the case... if not I would get hold of a wet vac and a cleaning solution called autosmart biobrisk... spray a diluted mix of the solution, preferable containing an APC too, onto the affected area, agitate with a stiff brush and then wet vac the solution out of the material... the material will be damp for a while but should dry completely within a day or so.
