How do I care for my Oyas?

Like anything, the better you care for your Oyas the longer they’ll last. Care is simple: Just pull Oyas up before the ground freezes, clean them off (a stiff brush or a 1:10 vinegar solution will do the trick) and store dry. 

Regular cleaning retains the porosity of your Oyas, and any water in the walls of the Oya will expand when frozen and could crack your Oyas.
