jwestbury Posted January 30, 2023 Share Posted January 30, 2023 I went to St Leon Indiana, and I had a pretty good haul!!! Spent the day out there I have several fossils that are from the Ordovician time period and they’re in limestone, limestone shale. Does anyone have any good tips on washing them? Do you prefer dry? Just with a brush? What about any rusted stuff, do you use oxalic oxide? What about algae? Do you prefer water? Soap and water? Hydrogen peroxide? I’m afraid and don’t want to ruin any. Thank you!

ClearLake Posted January 30, 2023 Share Posted January 30, 2023 Most Cincinnatian material is pretty hardy. You are unlikely to do any damage using a toothbrush and water and giving it a good scrub. I’d be gentle is you have a fragile trilobite, but even most of those from there can take a gentle brushing. 1 Link to comment Share on other sites More sharing options...
