So I found a few rocks in my backyard (actually have a ton of lava rock pebbles) but a few of them have some dirt that is relaly compact. I already boiled them for about an hour but the dirt remains on the rocks. Is there anything I can do that will clean the rocks off besides scrubbing them for hours?
Also, I did a vinegar test but am not quite sure what I should be looking for? should I look for bubbling or foaming?
TIA
