Recently moved into a new house, it has a gas fire with some real coals on it. I've never had a gas fire before, it's lovely and warm but stinks when it's on, it's been checked and is safe but just stinks. It's been on quite a few times so I don't think it's dust, I've vacuumed all the crevices, could I spray a mixture of essential oil and water on it to make it smell nice or is this a big no? Don't want to burn the place down or choke us all!
