My ex had an heating oil leak in the boiler house which is adjacent to kitchen wall. There is a strong smell of oil now in the kitchen, and the kitchen unit beside the wall next to boiler house is stained. I understand that it can be a major problem to get rid of this smell which may involve ripping out kithcen units, chipping away plaster, etc.. Anybody have any ideas of less drastic action that could be tried before going this route?
