Disclosed is a method of removing synthetic and natural resins from an article containing an epoxy resin without damaging the epoxy resin. The article is contacted with a solvent having the formula where n is 1 or 2, which dissolves the synthetic and natural resins and forms a solution. The solution is then separated from the article. The solvent can be recovered from the solution.
