Slate & Shell (and Goban) Care Instructions

I’ve put together a pretty comprehensive guide to cleaning and caring for traditional go equipment. From slate and shell, to bowls and boards, I’ve learned a lot and will keep updating it as I learn more. I’d be interested in any feedback you have!


I am confused by these instructions. It may be that terminology varies but I think clarification would be worthwhile.

Firstly we have:

“Don’t use bleach, at all, ever. You’ll permanently dull the surface.”

Then soon after we have extensive discussion of h2o2(hydrogen peroxide) and using it to clean the stones. Hydrogen peroxide is a bleach!!!

That’s a good point!

In the US I think we generally understand the term Bleach to mean a Chlorine-based cleaner. I’ll update the instructions to clarify the difference.
