The way I see it, if you have any trace oil, anywhere, there might be a problem, regardless of what Laurel Mtn. says. I don't use acetone, lacquer thinner or other petro chemicals for final degreasing, if there's any oil present you're just thinning it. Hot water and dish soap first (2x), hot rinse. Boil in TSP solution, boiling water rinse (2x). Final degrease with undiluted Simple Green, boiling water again 2x. Might be overkill, but I've never had a problem from residual oils with this method. They way I see it, there's no such thing as too clean. Clean, oil free cotton gloves are a must.
