Anything I've read recommends Tung oil and regular maintenance. The finish is water resistant only, so spills must cleaned promptly. Also trivets must be used with hot pots and be careful with metals as they could stain. That's the downside, the upside is the top will develop a beautiful patina over time along with great character..

I'm Scottish, you don't know the meaning of frugal LOL!! It's starting to get expensive to bring stuff from the US, dollars down, stamps are way up, EBay's Shipping is a ripoff..
Anyways, have a Merry Christmas, Taco
