Yes. Any paint department or paint store. I mix it 50/50 with mineral spirits. Keep it in an old mason jar. I have several old metal baking pans I use to soak my projects in. Let them soak for five of ten minutes, then wipe off the excess with a clean lint free rag. I use old tee shirts for this. I use compressed air to blow the oil out of small areas. I let the project dry on an old baking rack. Let the project dry for a couple days, depending on humidity, Then I topcoat with a semi gloss spray lacquer.
Make sure you don't leave your oily rags in a pile. lay them flat or hang them across a trash can till dry. The oily rags will build up heat and start a fire if they are piled up!
When I am done soaking I pour the oil back into the mason jar with a tight lid to keep it fresh for next time.
