Advice for using tung oil onj kitchen work surface
I was hoping for some advice on using tung oil on a kitchen work surface. Specifically I want to fix up the surface - as it is dirty, discoloured and in some places the finish has been gouged.
The wood has had a tung oil finish from the beginning (yes a real 100% tung oil coating not a varnish labelled tung oil). I have been every 6 months or so recoating it. But the surface has a few issues now I and I want some advice before I go forward with just slapping another coat of oil on. So here goes:
the surface has some "spots". It is a kitchen work surface and consequently sitting on it are a few appliances (microwave, blender etc). However the little rubber feet of the blender seems to have somehow marked the surface. I don't know if this is just in the oil finish or somehow marked the surface. And I am not sure how to get rid of these marks. (see the below photo)
The surface also has a few marks - like gouges - from moving appliances around. The last time I reapplied the tung oil I thought they would disappear. They didn't. Anything special I need to do to take care of these?(see the below photo)
Finally, parts of the surface have been covered - yet again thanks to aplpiances - while the front portion has seen more active use. As a result different parts of the surface are now different colours. Some of the more natural tone of the wood while others have the deeper oranger tone of the tung oil. What should I do to resolve this problem? Two photos here:
Thanks in advance for any advice and help!
