can’t decide about swapping stocks

I put together a woodsrunner kit a couple of months ago. Turned out nice but the carving is driving me nuts.
I never use any oil on any of my BP rifles,. After cleaning I wipe them down inside and out with bear grease. I am old and do not want to change how I maintain my guns after 60 plus years of doing it this way.
The bear grease leaves a white residue in the carving that a brush will not get out.
If you zoom in on the picture you can see it.
I would just order an uncarved stock BUT this barrel in this stock shoots as good as any BP rifle I have ever owned, I hate to change it.
I suppose I could order a Maple stock and hope it still shoots great but I would hate to spend $600.00 and it not shoot as good.

What do y’all think

Could you rub a little charcoal in the carving to stain the grease?

Just run it as is. That is what they would have done back in the day.

Or dont rub it on the stock ever time just do it once or twice a year
