Never tried this on a PSG1 grip, but it works wonders for guitar fretboards. And I'm pretty sure us guitar guys are more picky about our fretboards that you will be about your PSG1 grip.What is the best way to clean and care for the walnut palmshelf grip from the PSG1 trigger group? Mine is getting pretty ratty and im worried about damaging the wood by cleaning it improperly.

Naphtha .. i.e. Zippo lighter fluid.
It is gentle on typical wood finishes, will easily dissolve dirt and oils, and evaporates quickly so it doesn't expand the wood. It won't react with nylon, so a nylon bristled brush can be used to scrub into tight places, like the areas of the frets on a guitar, or the texturing on the grip.
Probably its overkill. A nylon brush and some soap and water would likely be just as good for your purposes.
that's funny you like the smell as most don't, but I agree it has an old wood shop smell I enjoy it and as you said it won't hurt anything on your rifle.I do not own said grip.... however I am a woodworker. Ballistol was mentioned which I use liberally (I also love the smell, its nostalgic). You can also test a hidden area if you have one that is not seen.
