Okay... I've seen that there has been mention of Iron Out/Super Iron Out in the forum. I know there's a chemical difference between the two. And, even though Super Iron Out seems to be the preferred product here, both contain Oxalic Acid which is the chemical that primarily removes the rust stains. I got a really good deal on a 28oz bottle of Iron Out powder ($3.96), so I'd like to use that to start. My question is, for normal purposes - rust stains on white quartz, for example - what strength do you all use?

The person I spoke to said that they were the same. That seemed odd but I have not noticed any difference in the two. Actually all I can find these days is Iron Out. I cannot find anyone selling Super Iron Out, not even Amazon. You said bottle, is yours liquid or powder? I use the powder version, not the spray. |

When I cleaned up the ones we dug up from Diamond Hill Mine, I used whatever the bottle said. I think it was 1 cup per gallon. Or maybe it was 1/2 cup per gallon... I don't quite remember. The point is I just used what the bottle said. |

Most big box stores have the SIO powder on the shelves here in Canada in the section where they sell cleaning products. |

I can only buy Super Iron Out around me. I don't measure, as it is pretty mild on most rocks. I put my rock into water (warm water works a bit faster) and dump in a small amount of powder and watch for the reaction. I pull out the rock when it is done and rinse it off or add more powder if I deem the solution to be weak. I usually take out the rock after less than half an hour. I am cheap, so try to use as small amount of powder as possible. It works quite well to remove iron or some other stains. I don't use it on quartz, unless I want to keep hematite. Quartz is not affected by muriatic acid, so I will use diluted muriatic on quartz. Muriatic will remove the hematite.

I just use cheap Oxalic. The key here is that the concentration is more of an issue with how long you want it to take. Also if you heat it, it works faster. I just dump in a couple of handfuls and use a stainless stock pot over a couple of hot plates. After pulling out the cleaned rock rinse well and let the acid evaporate till you are back to crystal and store. put a non iron screen over the top and let the sun dry it.

  This was done with a half a cup poured into about 2 gallons of hot water in a 5 gallon bucket. I left the pieces in there for a few hours, but basically it looked just like this the first time I checked it after an hour. I was really surprised how quickly it worked. It was also sitting out in the sun to help keep it warm. |
