Good Morning! We’re adding an addition in our backyard and found these while digging. For reference we’re located in Charlotte, NC so these were dug out of red clay. I believe it’s quartz but would love to know if it’s something completely different! Our son’s room is nature themed so these will later be used as decorations in there and would love to restore these little guys to their bright white glory. Any chance or recommendations on how to do so, or are they too stained from the clay? I’ve tried soaking them in dawn, and then a mix or white vinegar/water with dawn, and then scrubbed them with a toothbrush and this is how they currently look. Any help would be greatly appreciated!
