Many self-collected minerals from Quebec, Ontario, and northern New York are iron-stained as they come out of the ground. After soap and water, if there are still brown stains on silicates, Super Iron Out works wonders. I usually cover the specimens with water in a nonreactive Rubbermaid or Tupperware-type container with a lid to seal in the odor. I most often start with warm water, sprinkle in a couple tablespoons of Super Iron Out and then leave them overnight. In the morning, I carefully change the water with running hot fresh water and then add a liquid dishwashing detergent (I tend to like Ajax because it doesn't smell much). After giving sturdy pieces a quick scrub with a soft toothbrush, I use my Albatross 500 water gun to remove the remaining clay, etc. from little holes and crevices. If there are biologicals like lichens or roots, a soak in slightly diluted Chlorox does wonders. Generally I find that feldspars, amphiboles, pyroxenes, garnets, quartz, wollastonite, scapolite, titanite, and most other silicates are not changed by this procedure, except for losing their iron stain. Fluorapatite doesn't seem to be affected if it has high luster. Don't use this on goethite ps. after pyrite since the goethite will be dissolved away. Crystallized hematite is unaffected if low concentrations are used. For localities of specular hematite xls, the clay and mud that gets caught between the blades is freed up by short treatments with Super Iron Out and then a soft brush or a water gun does wonders. Calcite doesn't like Super Iron Out. If it is a weathered surface, e.g. Grenville Marble, it cleans it nicely, but makes the surface luster slightly more dull, i.e. from dull to really dull. Lustrous calcite xls are ruined by Super Iron Out. Fluorite xls are dulled slightly, but only slightly by this treatment. If it's iron stain or slight dulling, I usually choose slight dulling. Super Iron Out replaces the older Waller procedure with sodium hydrosulfite, sodium bicarbonate, and sodium citrate, works just as well, is much cheaper, and much, much easier to obtain.

This product works really well in my toilets. My well water is loaded with iron. It can also be used in washing machine and dishwasher.
