Hello Christoph, thank you for this video. I have one Ligurian stone I collected around 15 years ago. I kept it untouched until last year when I started cleaning it. I used a rotary polyamide brush so far. It is quite soft and I didn't use high speed so I didn't damage the stone, but there are some details I didn't reach yet. I will switch to a steel brush as you recommend and see the results.
Indeed brass brushes are a no-go - but I've collected and cleaned dozens of ligurian stones the largest of which is about 70 x 40 x 25cm - I would still sit there, if I would not have used a Dremel or even larger brushes when the clay layers were thicker than 2 or even 3 cm. I also agree that I woudn't use oil or talkum (like my good friend Willi Benz RIP suggested in his first book about Suiseki) - later he also stopped using any oil. I'm also not cutting the base of my stones, like many suiseki authors suggest and is common practice in Japan.
Thank you for your interest… Of course you can try - but with this stone, the wet dirt will get black like the wet stone and can no longer be identified easily! I just tried for you ;-))
Thank you very much for the tips you gave
You‘re welcome, more will follow… Thank you!

Thank you for your input and yes, I do agree… especially on cutting stones ;-))
For stones already clean Is ok.
What about keeping the stone wet during this operation ?
Thank you for your interest…
