This is a repeat post but including some pictures for comparative purposes -
I used Tung oil on my kitchen worktops, and one area that gets almost daily wiping and is exposed to spills from hot liquids is the area around my hob.
This was purchased/installed 5.5y ago and from memory had a total of 4 coats - 2 initial thinned 50/50 with white spirit and the final 2 applied with a rag rubber.
As supplied from Ikea - actually this is the cut-out from the hob -
Here 5.5y later adjacent to the most frequently used burner under natural illumination - you can see that the block on the corner is showing slight lightening where the coating has worn through daily wiping -
Here under artificial illumination - the line is the shadow from my hand from the overhead extractor lighting -
Tung oil is food-safe - it is used on commercial wooden kitchen stuff- salad serving utensils, bowls etc and it is super simple to either spot re-coat or re-apply to the entire worktop with a rag which if thinly applied will be dry enough for use if left overnight.
TBH the pictures make it look far more pronounced than it really is, and AFAIKT there is little to no discoloration/staining of the underlying surface so a recoat would restore it to as-new,
