I used my Bissel Green Machine on the seat a few times. That is generally less effective than hitting it with a spot remover and agitating it with a brush or something. And then the full on washing machine soak and all that tends to be a pretty aggressive attack, better than a carpet machine. The stain just really blew out that fabric. And I'd rather not do the nuclear option: no stain, but no seat cover either!Why not use something like a carpet cleaner machine? Need a super super strong sucker.
If you haven't put a hole in it, you have not try hard enough. I usually try all the safe stuff, than bring out the big gun like gasoline and nail polish remover. LOL By the time I'm done, there won't be any fabric left for the stain to stain. LOL
