Worktop Oil is designed for untreated or previously oiled/sanded wood surfaces. The oil makes the surface highly water and dirt repellent. Use Worktop Oil, Natural, on both dark and light wood species – such as mahogany, merbau, teak, cherry, ash, oak, beech, maple, birch, pine etc. - to give the wood a mellow, golden colour. Use Worktop Oil, White, to lighten up the wood or give it a whitewashed effect.
