Spot Testing With Cotton Swabs or a Damp Cloth

Different paintings may require other cleaning methods based on their materials and condition. Spot testing allows you to determine the most effective and safe cleaning method for your painting, whether a gentle swabbing with a clean cloth or a slightly more aggressive approach with a stronger art cleaning product.


Materials Needed to Clean Old Paintings

Soft-Bristled Brush and Cotton Cloth

The bristles of a soft brush and the gentle fibers of a non-shedding cloth are less likely to scratch or disturb the paint layers than harsher materials. Abrasive cleaning materials can cause irreversible damage to the coat of varnish, affecting its appearance and value.

Distilled Soapy Water

Distilled water is free from minerals and impurities that may react with the painting's materials. This minimizes the risk of chemical reactions that could alter the entire surface or cause permanent damage to an old oil painting.


Clean Cotton Swabs

Cotton swabs provide a fine and focused point of contact, enabling you to clean small or intricate areas of the painting with precision. It helps clean delicate details, textured surfaces, or hard-to-reach spots, minimizing the risk of damage and loss of vibrancy of the art piece.


Varnish Remover and Gloss Varnish

After removing the yellowing varnish and cleaning oil paintings, apply a fresh coat of varnish layer to provide a protective barrier. It can help consolidate and protect the paint layers, preventing them from becoming too dry or brittle. However, using varnish types requires expertise and experience, mainly when working with valuable or historically significant canvas paintings.


What to Avoid When Cleaning Old Paintings

Using Stiff Brushes or Paper Towels

Stiff paint brushes and paper towels can scratch the surface of the painting, leading to the loss of paint particles or even entire paint strokes. Additionally, abrasive movements can irreparably damage paintings on canvas and diminish their artistic and historical value.


Applying Excess Water

Some paint pigments, especially in older paintings, can be sensitive to moisture. Excess water can cause pigments to bleed or migrate, leading to color distortion or even paint removal. If not properly removed and dried, excess water can leave residues, streaks, or water stains on the painting's matte surface.


Hiring Untrained Art Restorers

Cleaning an old painting is a highly specialized field that requires expertise. A professional art restorer deeply understands art history, specialized products, techniques, and the science behind conserving an aged oil painting and other mediums. 


Maintenance and Preservation

Consulting with a professional restorer is highly recommended to ensure you take the appropriate steps to safeguard the artwork for future generations. Proper care and preservation efforts can help old paintings retain their beauty and cultural significance for years.

Regularly inspect the painting for deterioration, such as flaking paint or cracks on the protective glazing. Early detection can help address issues before they worsen.
