I have an untreated pine table in the kitchen and from time to time I stupidly allow a cigarette to burn it - before the wife gets home I sand it all over with an orbital sander and largely remove the burn mark - then I dress it with teak oil - I have a 5L tin for these emergencies.
She thinks I'm a wonderful person for taking so much care of our kitchen table.
Following some negative feedback I now do the sanding outside.
