Did not notice I had grease on a rope. Well it stained my bench seat that I had reupholstered a few seasons ago.
So far:
Let boat bling vinyl sauce sit on it and lightly scrub with a tooth brush several times. Let the cleaner sit on it over night and done the same thing.
With the cleaner and it sitting in the sun for about 5 hours yesterday, a lot has came out.
I’m letting dawn dish washing liquid sit on it now.
I know not to use a magic eraser.
Any other suggestions? Think the sun will eventually take it out or is it ruined?

I would stop putting anything chemicals on it at this point. It looks like the shiny finish is already partially rubbed off. Merc HP gear lube will stain similar to this. I've had stains from it and eventually the sun bleached it out, but it took a most of a Summer before it was gone completely.

Dawn on the stain is making it look that way.
Glade to hear the sun eventually should take it out!

Did you try Simple Green?

For grease I use these. Won't dry out the upholstery either. (truth be told I use these for all kinds of stuff in the shop)

As Griff said above, let the sun do it's magic. I've seen it take out stuff I'd never thought would come out.

I haven’t tried simple green.
Star Brite done a good job in the past. I’m going to try that then the tub o towels. If that don’t work, I’ll let the Sun take care of it.
Lake Cumberland Poker Run is less than 3 weeks away. I’d like to have the stains gone by then.

GoJo works wonders...

Super Clean or Awesome from the dollar store works great.

I've used soft scrub and just let it sit on there for a bit of time.
