A mixture of one part lemon juice to two parts olive oil is brilliant on butcher block table and counter tops and rustic, low lustre furniture. Definitely not for use on fine furniture as it will remove the patina but works well even on polished floors.
Use the cheapest olive oil you can find, it really doesn’t need to be EVOO.
I keep it in an old Grolsch bottle as it doesn’t emulsify so you need to give it a good shake before starting and at intervals whilst using it. It’s easier to do and undo the top single handed with a wire snap closure.
I find it good at cleaning and the lemon juice also seems to stop it darkening the wood over time. Just wipe over liberally, wait a minute or two, then wipe off any excess.
Smells nice too.
