I own one of those Scott. It might do for cleaning rocks but it's pretty flimsy and awkward to handle. I bought mine to wash cars but found it too much of a hassle to use so it now sits in the garage gathering dust.

Haha, thanks. I need a tumbler more than a pressure washer though. I only found a few rocks, but I have boxes of tumbled rocks for use...and plenty of jewelry for tumbling.

Here's a couple examples of the iron staines. I thought they were clay. It's probably tiny cracks with clay...and then some iron staining. I'm pretty new to this still. So much to learn.

I soak all my iron stained stuff in hydroxide peroxide and baking soda combo. Leave it outside in the sun for a few days, i think the heat helps but that could just be in my head. If thats not enough i soak it in iron out. If that doesnt work that means the iron isnt stained its a part of the mineral composition of the stone and nothing will get it out. Those pics look a lot like what i find in my area, i can get quite a bit of the exterior stains off using both methods but the tiny cracks youll have to grind those off to get the stsins out

Wow, thanks! Two ingredients I know how to find, know how to use and won't kill me from the fumes alone. I'll try it next week once I have some HP and find a bucket. What quantities/ratios do you use?

resurrecting an older thread - can oxalic acid be used in an aluminum container? My thoughts were to use a beer keg and a turkey boiler to warm the water. Or is stainless steel better?

Barkeeper's Friend contains oxalic acid and works fairly well. I have had zero success asking for Oxalic acid by name- folks just kinda give ya a blank stare. I think it's one of those formerly common inexpensive chemicals that got absorbed into some corporations product, so that they can charge more for it. Even Borax, the younger generation has no clue or have never heard of it. Anyone remember buying calcium carbide at the hardware? What fun stuff that was... LOL, I still have a container of calcium carbide and an old carbide miners light in my basement.
