To clean paint by number oil paintings, start by gently removing loose dust. For more ingrained dirt or areas with texture like ridges or impasto, a soft toothbrush can be used carefully.
Keeping your paint by number oil painting clean helps preserve its appearance over time. Dust and dirt can dull the colors and, if left for long periods, can potentially cause damage. Cleaning should always be done gently to avoid harming the paint layers or the canvas.
Basic Cleaning Steps
Based on methods for cleaning oil paintings, the process typically begins with removing surface dust.
-
Gentle Dusting:
- The initial step is to dust off the painting.
- You can use a soft, dry brush (like a clean, natural-bristle paintbrush or a soft dusting brush) or a microfiber cloth.
- Brush or wipe very lightly across the surface, working from top to bottom, to remove loose particles.
- Avoid pressing hard, as this could push dirt into the paint or damage the surface.
-
Addressing Ingrained Dirt or Textured Areas:
- According to one reference, if a painting has "a lot more ingrained dirt" or areas with "thick ridges and impasto built up techniques," you could potentially use a toothbrush.
- Caution: Use this method with extreme care on oil paintings, especially older ones or those with delicate paint layers. A soft-bristle toothbrush would be preferable.
- This method is likely intended for carefully dislodging dirt from crevices within the texture, not for scrubbing the entire surface.
- Test in a very small, inconspicuous area first if you choose this approach.
Important Considerations
- Avoid Water and Solvents: Unless you are a professional art restorer, do not use water, soap, or cleaning solvents on your oil painting. These can cause significant damage to the paint and canvas.
- Check for Damage: Before cleaning, inspect the painting for any flaking paint, cracks, or tears. Cleaning a damaged painting without professional knowledge can worsen its condition.
- Professional Cleaning: For valuable or heavily soiled paintings, consider consulting a professional art conservator. They have the expertise and materials to clean paintings safely and effectively.
- Varnish: If your paint by number painting has been varnished, the varnish layer protects the paint and is what you are cleaning. However, varnish can also degrade over time and yellow, requiring professional removal and replacement.
