hey, so i am fixing up my supra *just bought it on saturday... 4 days ago* and i was on the interior stage today. i vacuumed the whole thing out really well, but the whole thing is a bit brownish because it is dirty. dont get me wrong.. the interior is really mint, very nice, but i want it to look new. What products and cleaning methods have you guys used on your supras? I wanna get this looking mint.
