Cleaning a wooden table the Medieval/ historical / natural way!

Can I use this method to clean my Dishes? My Dishes are ceramic, metal, and glass. Will it ruin anything?

This was very interesting! The salt, of course would kill germs, and the boiling water would get rid of anything else. I like your demonstration. ~Janet in Canada

Waste SALT on this?!
Sand surely!
How did ppl have $ for salt to waste, not eat

this has me wondering could i clean my floors like this

Such a simple thing is surprisingly engaging. Thank you for the demonstration!

I can see this on cutting boards in the modern age
