Cleaning rocks with different acids (Finding Gold specimens!)

We experiment with five different acids to clean rocks and gold specimens from the Blue Chip Mine. We are trying to see which does the best job in creating a great looking gold on quartz specimen. We use Iron out, CLR, Oxalic acid, Muriatic acid (Hydrochloric acid) and nitric acid in this experiment. Warning! I do not recommend you try this yourself as I do not know your knowledge, skill, or safety levels.
