30 years ago, I developed a simple process for treating these rusters using white sodium hydroxide crystals (Red Devil Lye which can be bought at most groceries), 70% rubbing alcohol and distilled water.

With it I have treated effectively meteorites up to 150 lbs.

I have sitting in my corner a 150 lb Campo that was rusting so badly that I could hear the flakes popping off and falling to the floor.

Pounds of rust flakes fell off of it.

So, to solve this problem I rolled and muscled the 150 lbs ruster into the plastic shipping container and righted it up.

And I used my solution tried and tested with many variations over the last 30 years.

1lb Red Devil Lye (white crystals)

Two gallons of store bought rubbing alcohol. (Usually in plastic bottles of quart size for less than $2 ea)

Two gallons of distilled water.

And a medium sized plastic shipping container with lid.

Mix half a pound of Red Devil Lye in 2 gal of water. Do it in small amounts as the reaction is exothermic and the water will get hot.

When done, mix this into the two gal of rubbing alcohol.

You will have the remaining half pound of lye crystals to add if you decide to repeat the process a second time, or you can add increments more till you see that brine begins to form what look like bubbles at the bottom of the plastic container.

Then I poured the solution into the plastic shipping container holding the 150 lb Campo, and covered it with the plastic lid.

And...

I let it sit for a year. Yes, that is right, a year for big specimens.

Over that time I monitored it to see the progress. Numerous green blobs appeared over the meteorite. I could see streamers of rust coming off of it. And the solution at the bottom of the plastic container took on a rusty hue. And so I let the process work for a year.

Result...

Used a plastic hand pump to remove the tainted solution. The chlorides that caused the meteorite to rust now converted to NaCl (salt) in solution, taken out.

I then replaced it with two gallons of distilled water to further remove the salty water and residual NaOH. Let is soak for a couple of weeks. Repeated the process for another couple of weeks.

And finally rolled the 150 lb Campo out to dry and for the last 7 years it has sat in my corner, no longer popping of rust flakes.

It is cured, and actually looks like it was freshly dug up and cleaned of dirt.

Now I recently tried another ruster: Morasko.

I have 690 gm complete specimen that started to rust. Placed it in a a small batch of my solution and let it sit for several months. It was cured. But in this case I did something else with it. I put a piece of zinc off to the side of it. This actually caused an electrolytic reaction where the Chlorine ions were attracted to the zinc and the zinc in turn became a deposit on the meteorite giving it a rather un-natural appearance. So to correct this, I then soaked the Morasko in white vinegar for a week, and the result was a natural looking piece.

And non rusting.

So I have used this on not only these rusters and some pallastes, but even a mesosiderite, the notorious ruster, Lamont, KS, one that I discovered in 1996.

I have used it on iron slices, too.

Depending on the size of the specimen the soak time varies. Small thin pieces a couple of weeks. Really big ones such as the 150 lb Campo a year or more.

In all of these cases it worked.

The tech is free to all.

Try it, you have nothing to lose with a meteorite that rusting away anyway.

Hi Greg and List,

You won't regret contacting Pat. I'm not saying that Pat is some kind
of magician, but his results are almost "magical".

For example, I will give an example from a fellow List-member's
experience. This person can chime in if they want, but I won't
mention the name because this person has no idea I was going to offer
up a testimonial on their behalf.

Having said that, this person bought one of Pat's Campos that is about
the size of grapefruit. This Campo now resides in one of the wettest
climates in the Western hemisphere. In addition to the wet location,
this Campo is used in outreach/educational work and it comes into
contact with dozens of sweaty little kid hands on a regular basis.
After over a year of this exposure, the specimen still shows no sign
of rusting.

Another specimen went to a prominent amateur astronomer (not a list
member) who uses the Campo in outreach work also - again, this
specimen comes into contact with sweaty little hands and is kept out
in the open without any special precautions to prevent rust. And this
specimen also shows no signs of rusting after several months of this
kind of "abuse".

Pat's process also works on pallasites and I have sold a few of these
specimens to buyers in various locales - and all of them are pleased
with the stability of their pieces.

In the interest of full disclosure, I should state that I do get a
kickback from Pat for the business I refer to him. But, I am
blatantly honest about meteorites (to the point of pissing off a lot
of people) and I would wholeheatedly endorse his process even if I was
not receiving a kickback. I love meteorites and I want all meteorites
to be preserved and cherished for generations to come. I think it is
a noble endeavor to save these hopeless rusters from oblivion and it
is my wish that Pat's process should see widespread use to save
specimens like Admire from a horrible fate. I'd much rather see an
Admire mass saved through Pat's process, than to see it dissolved in
acid and rendered down into a pile of olivines.

I think most people would agree, that on an aesthetic basis, Admire is
a beautiful pallasite. If it's propensity to rust is removed from the
equation, then Admire could hold it's own against any other pallasite
on the market. The same could be said for Brenham also.

I'd love for the skeptics to try Pat's process and try to make a liar
out of me. I truly believe, in due time, Pat is going to become
well-known and respected for his work. As of right now, he is not
widely known and he is much more available for work. Once word gets
out about the effectiveness of his process, I fully expect there will
be a long waiting-list for his services.

Imagine a world full of stable Nantans, Campos, Droninos, Admires, and
Brenhams! That would be a great thing and I hope more people will try
Pat's process and see for themselves.

Best regards,

MikeG
