ooo man... find some one with a steam cleaner... my g/f owns one and it made a BIG difference... it takes out everything!
i think that is what i'm going to end up doing. this morning i looked at the passenger seat i cleaned (after it was completely dry), and while the actual stains are gone, most of the dirt is still there. it doesn't look quite as blue as it did last night and it's showing a
slight yellowish color. i guess that's just 16 years of dirt buildup in the fabric and i think only a steam cleaner could get that out.
still though, the Tuff Stuff worked GREAT for the stains and as a pre-cleaner.
