Composite stock cleaner(s)?

[game4lunch]

My Ruger M77 "All Season" composite stock is very hard to clean.
Any suggestions?
I've used Simple Green, dawn, various other cleaners, and even ascotch brite pad. I really don't want to scratch it up, but there is still a grimmy feel and look to the hard-to-get-to corners and grip area.

Any magic product out there that has succeeded for yous guys?

I think it's just the nature of the beast. It will never feel like a smooth wood finish.

Try some acetone or finger nail polish remover .Then wipe it down with an oily rag.When I put the camo tape on my compositem stocks and leave it for a year or two.It removes all of the glue residue. Does a pretty good job.

Really? I'd be afraid the acetone would react to the stock material. I have used various solvents, and expecially like turpentine, but still no luck.
