Care of oil paintings

How should I store an oil painting?

Oil paintings should be stored in a dry, well-ventilated room at a constant temperature (ideally 18–21°C) and humidity (approximately 45–55%). Avoid direct sunlight, high humidity, and extreme temperature fluctuations.

How do I clean a dusty oil painting?

Light dust can be gently removed with a soft, dry brush (e.g., goat hair) or a microfiber cloth. Do not apply pressure. Never use water, cleaning agents, or household remedies.

Can I clean a dirty or yellowed painting myself?

No. The cleaning of heavily soiled or yellowed oil paintings should be left to a professional restorer. Incorrect cleaning attempts can permanently damage the artwork.

Should an oil painting be framed?

Yes. A frame protects the painting from mechanical damage and environmental influences. Make sure the painting is not directly against the glass surface when using glazing (e.g., with spacers or museum glass).

How do I protect an oil painting from sunlight and UV radiation?

Do not hang oil paintings in direct sunlight. UV radiation can bleach colors and make the varnish brittle. Indirect, diffused lighting or special UV-filtering glasses or lamps are ideal.

How often should a painting be re-varnished?

A varnish protects the painting and intensifies the colors. Over the decades, it can yellow or become brittle. Renewal should only be performed by a professional conservator—approximately every 50 to 100 years, depending on the condition.

What should I do if there is damage such as cracks or peeling paint?

Contact a qualified restoration workshop immediately. Never attempt to repair such damage yourself—this could cause irreparable damage to the artwork.

Does it make sense to insure an oil painting?

Yes. Art insurance is particularly advisable for valuable or sentimentally significant paintings. Document the work (photos, description, provenance) and keep all records carefully.
