How do I clean 'rusty' rocks?

19 years ago

I hunted for dozens of nice rocks last year, hauled them home and then landscaped and planted around them. I then watered my new garden and discovered my outdoor hose did not go through the rust filter and all my rocks are rust colored. What can I do to clean them up? Is there a chemical or something I can use to clean them???/

    The problem may not have been your hose, but the rocks. If the rocks have iron in them & they get wet, the iron can precipitate out & you will see rust. I have had the same problem with some of my rocks, & am placing the iron rocks in areas that do not get water.
    You could try sanding them with a light abrasive. In the desert, that is how nature cleans them.

    No, these definitely are rusty from the water. I've now put a new iron filter on my "outside" water and should have no more problems with that. But thank you for the abrasive answer... I will try that. THANKS!

    I was double checking my planned strategy to clean some excess flaky dulling deposits on some surface collected quartz crystal, so I used google and ended up here. For years, I assisted the proprietor of a rock shop lapidary service. I want to thank eggers00 even if it was back in 2006 for the comprehensive procedures that I know first hand work well.

    Amen to that. What a comprehensive and well-explained answer.

    I have a small boulder size Michigan Pudding Stone. Its background is a creamy grey quartz. It has a glorious mix of red jasper, a dark brown, and a dark denim blue stones that cover the entire rock. In the middle and near the top is an egg sized spot of rust. Orange brown rust. Very distracting. There are other smaller spots of rust along one side. I could live with those. The large one distresses me. How can such a large rock be treated?

    I have rust on the fireplace stones. How do I get that off?

    This is a gardening forum, you may want to ask that in the cleaning tips forum

    Or the fireplace forum
