I have this ammonite from Portland, Dorset. (Titanites sp?)
Q: Is there a method for cleaning carbon staining without compromising its surface? Its been exposed to the elements since it was found in 1986.
Its about ~1m in diameter, tennis ball for scale.
Currently residing in the garage, until I work out how to sneak it in the house[biggrin]

Hello and welcome to the forum. That's a lovely find. I would find someone very near you that has the air tools to do it for you. It looks to be in very good condition

Thanks!
Would sand blasting be too harsh? (Speculation, I know nothing about it)
Unfortunately, I don’t have access to air tools- but can rent a steam cleaner if that would work?

no don't do that, this ammonite deserves professional prep and is worth the money it will cost to do it right.

Don’t worry, I’d never do anything like that![biggrin]
Believe me, I'd prefer to leave it as is rather than risk losing detail and spoiling it.
I am quite keen to do this properly

Maybe a treatment with bleach could work. I usually use it with shells, to clean them up.
Try a little patch on the rear side.

Very nice fossil!
If you’re based in Dorset there’s plenty of very competent preppers in Charmouth / Lyme area. It would be money well spent. Soaking in 5% bleach will clean any algae off. Having said that it looks great as is, stains and all - has an “honesty” in the presentation. How are the centre whorls under the tennis ball?
