how do you clean dirty oil paintings?

Dust the surface very lightly with a soft, dry brush. Never use water or household cleaning sprays, as moisture will penetrate the fine cracks and lift the paint layer. If the varnish has yellowed heavily, leave the removal to a professional restorer. They use specific solvent blends tested on small corners to dissolve the old layer without harming the pigments beneath.

My grandparents left me a large portrait of a gentleman in a red coat, but there is no signature anywhere on the front. Is it still worth hanging up?

Most antique portraits from the eighteenth and nineteenth centuries lack a signature. Artists often viewed themselves as tradesmen rather than celebrated figures, so they left their work unmarked. A plain surface without a name does not diminish the decorative appeal. A well-painted provincial portrait still offers a strong focal point for a room, bringing history and character to your walls. Look instead at the quality of the face and the condition of the canvas. Strong eyes and a detailed costume matter far more to collectors than a signature.

what does relining a canvas mean?

Relining is a structural repair used when the original fabric becomes too brittle. A restorer attaches a strong new piece of linen directly to the back. This stabilises the tension and stops flaking. You can spot it easily, as the reverse of the canvas will look far newer than the wooden stretcher.

I noticed the painted surface has a network of tiny cracks all over it. Should I try to fix this or just leave it alone?

That network of fine lines is called craquelure. It happens naturally as the oil layers dry, shrink, and expand with the underlying canvas over many decades. Leave it exactly as it is. Attempting to fill or paint over these small fissures ruins the historic surface of the antique portrait. Collectors actually look for this pattern. It provides character, confirms the age of the materials, and shows the painting has survived without heavy-handed interference.
