Hi, if you use a traditional bench stone and use say oil instead of soaking it in water, do you need to continue using that same lubricant or can you use water one time oil the next etc ?
I use water or a mix of water and a Simple Green non toxic cleaner on all my oil stones .
I boiled my used oil stones in a pot of water to get the oil out , after a couple of water changes not scum appeared and they have worked fine for me YMMV
