Your oil paintings are an investment—both emotionally and financially. To keep them looking their best, keep them out of direct sunlight and away from extreme humidity. Dust gently with a soft, dry brush or microfiber cloth. Avoid using cleaning sprays or water directly on the surface. If you notice any flaking or damage, consult a professional art conservator. And when hanging, use proper hardware and consider adding a protective backing. With a little care, your oil paintings will bring joy for generations.
