Purification of minerals with oxalic acid

For many mineral collectors it should be a familiar problem - iron oxide crusts or deposits on crystals. In rare cases, it gives the look a special charm but usually it hides what you want to see. As a rule, no mechanical cleaning helps but chemistry is necessary. In this video I show you the effect of oxalic acid. To test the effect, I did not take showpieces but samples with particularly strong crusts. You have reviews or questions? - Leave it to me in the comment columns.
