Can I clean a dirty oil painting myself?

Surface dusting with a soft, dry brush is generally safe for an antique oil painting. You should use a clean, natural-bristle brush and work lightly across the surface to remove loose dirt. Avoid applying any pressure that might flake the paint. Anything beyond light dusting requires a professional conservator. Household cleaning products or water will cause irreversible damage to the varnish and the canvas beneath.

I have an old family portrait with a tear right through the sitter's face, so what are the options for repairing a hole like this?

A conservator can mend tears by patching or lining the back of the canvas. They align the broken threads under a microscope before applying a stable adhesive to hold the structure firm. Once the canvas is stable, they fill the gap with a synthetic chalk mixture. The missing section is then retouched using reversible conservation paints, ensuring the new work blends with the original surface.

Do antique oil paintings need glass?

They rarely need glass and historically sit open to the room. The varnish layer provides all the necessary protection against dust and minor abrasions. Adding glazing alters how the texture catches the light. If you do add glass, a spacer must keep it from touching the paint surface.

The painting is loose in its frame and rattles around every time someone shuts the door, is it safe to tape it into place?

Tape is a terrible idea for securing any canvas. Adhesives break down over time, leaving a stubborn residue that damages the wooden stretcher and the frame. Instead, use small brass offset clips screwed directly into the frame. These hold the stretcher securely without piercing the antique wood. You can pad the metal contact points with small pieces of archival felt. This stops the rattling and protects the stretcher from wear.
