Today I went out and found a bunch of rocks to do diy caves and such. I scrubbed them and boiled them so I know there's nothing living on them but some were very dark black and I think that may be from oil. The ones that clearly had oil on them I'm not using but there was one very dark one that didn't change when I scrubbed or boiled. Do you think they'll be save?
