Hey everyone! Just celebrated my daughters 2nd Birthday this weekend w/ a party & she decided to celebrate it by popping the straw out of her chocolate milk container & making a wee bit of art on the headliner of my ram. Now how & what does one use on this material to clean it? It's a soft fabric so I'm apprehensive about brushes & other tuff stuff also it's light tan so I'm scared of discoloring it. Help!!!!
