I found it in a rock pile at work. It’s pretty heavy I’d say nearly 90% is all geode. However as you can see it’s been roughed up scraping against rocks. My question is how do I polish it or get rid of all these white scrapes?I’ve googled but none really gave me definitive answer

One old trick to reduce the 'scruff' marks on many quartz-family pieces is a quick rub with mineral oil, won't eliminate them and it's not permanent.

Dude thanks for the instant reply….and input….so would it be a sin if I used something smooth it?

[James Catmur]

You could polish it, if you want. Not a 'sin'

It could be polished with many things, as James said.
But, even not been a sin, I think it looks far nicer as it is... At least from photo (and according to my taste, that should be said)

This looks more like a cobble of Calcite or possibly gypsum rather than Quartz. See if you can scratch it using a pocket knife or nail.
