Removing fuel oil odor involves opening the windows to ventilate the area, looking for an oil leak or spill, absorbing the spill and cleaning it with a degreaser, according to OzoneSolutions.com. HowtoCleanStuff.net recommends placing ground coffee in bowls around the area to absorb the odor.
Air out the area
Open windows to air out the home, and use fans and dehumidifiers to help dry up any areas of spillage. Placing bowls of ground coffee or activated charcoal, which is available from a pet store, around the space helps to absorb lingering odors, according to HowtoCleanStuff.net.
Soak up spills
Any leaked or spilled fuel oil should be absorbed with oil-drying product used in automotive garages, as explained at OzoneSolutions.com. Give the product some time to absorb any remaining liquid, then scoop and sweep up the product for disposal.
Clean the area
Clean up the area using a cleaning agent with a degreaser in it, or use a cleaner specifically designed for odor removal, such as Odor Medic. HowtoCleanStuff.net describes a commercial product called Odor Kill, available from fuel oil providers, and also recommends asking the fuel company about additives that can be added to the fuel tank to help prevent odor.
