Danish Oil is perfectly fine for kitchen worktops and has always been one of the more traditional oils used. Wood oil technology has moved on over the years with new types of oils that are much more durable, longer lasting and only require 2 coats, as apposed to Danish Oil, Teak Oil or Pure Tung Oil, that require more coats and more frequent re-application to maintain the finish.
Our recommendation would be to look at the range of 'Worktop Oils'. They are extremely tough, durable, stain, scratch and water resistant. They are very easy to apply, maintain and patch repair if a particular area becomes worn or damaged.
An alternative to 'worktop oils' are the range of Hardwax Oils. Hardwax oils are as durable and long lasting as top oils, are available in clear and a range of colours, are also food and child safe when dry and equally as easy to apply, maintain and repair if required. If unsure about a particular colour try one or more of the Hardwax Oil samples.
To prepare the wooden worktop it may be necessary to strip the old Danish Oil finish by either lightly sanding the surface or wiping down with a clean, uncoloured cloth dampened with white spirit. Once the worktop has been prepared as above, simply apply 2 thin coats of Top Oil to the surface following the manufacturers preparation and application instructions on the tin. If the worktop is made from a dense exotic hardwood such as Teak, Mahogany, Ipe or Iroko, it may require an extra thin oil like Osmo Wood Wax Finish Extra Thin (1101) to achieve maximum penetration.
