Wood Kitchen Worktop Oil. This species is VERY poor for a kitchen worktop because it contains naturally-occuring tannic acid which will destroy meats. That does mean that your countertop will absorb a phenomenal amount of it and that you'll be oiling over Are you sure it is oak?!
Hardwood worktops should be given at least three and usually five thin coats of protective wood oil - if possible, before they're installed. Wooden Worktops should be oiled twice a year or when there are signs that they are no longer water-resistant. Do not use traditional kitchen cleaning products on your work surfaces as this can stain the wood.
A solid wood worktop adds warmth and atmosphere to kitchen.
The oil makes the surface highly water and dirt repellent.
Mineral oil does not polymerize at all, it just soaks in. It is also beneficial to apply as many coats as possible to the end-grain of the worktops as this is the area. Nourishes wood while protecting against water and harmful bacteria.
