removing water marks?

[bundy]

have done a couple of searches and no luck,

on my passenger seat i have a big water mark/stain, any ideas what i can do to remove it or reduce it? has been there a while now

hire a goarge wet vac or equivelant and do it yourself or find a good valeter/detailer who will have all the correct equipment/chemicals to remove it properly
