An oil spill which occurs in a house could create a contamination problem, which can be difficult to correct. Peat moss can be used to remove floating oil. If only finished basement walls have been affected, the odor can be eliminated by removing and discarding the wall covering, studding, insulation and any other permeable material.
Use caution when using electrical equipment during cleaning since the fumes could ignite and cause an explosion. Dispersants should also be avoided in cases where oil tanks have been ruptured.
