how to protect plywood over dishwasher - mineral oil?

Hi,

I'm overthinking this. Granite counter sitting on plywood over dishwasher - worried that dishwasher steam will hurt plywood.

I know metal tape and painted on varnish/polyurethane are options. With those I've worried that if water gets behind and can't evaporate then that causes problems. With the painted on solutions, I'm afraid of stuff flaking near the dishwasher.

So...I asked my favorite paint store guy what he'd do and he suggested looking into mineral oil since it's food safe, won't flake off, and they use it to protect cutting boards.

I'd love opinions on this - sound like a good idea? what have others done?

Thanks
