An oil painting is not only an interior decoration but also an investment that can last for centuries. However, the canvas and paints require specific care. In this article, we’ll discuss how to care for an oil painting to preserve its vibrancy and integrity.

1. Proper placement: where to hang the painting?

The first step to preserving your painting is choosing the right location. Oil paints are sensitive to external factors. Avoid direct sunlight. Ultraviolet rays destroy the pigment, causing the painting to fade and the varnish to yellow or crack.

Temperature and humidity.

The optimal humidity for a painting is 40-60%. Avoid hanging the painting over radiators, fireplaces, or air conditioners. Sudden temperature changes can cause craquelure (microcracks in the paint). The kitchen is not the best place. Spears, grease, and steam quickly settle on the surface, eventually requiring expensive professional cleaning.

2. How to properly dust a painting?

Dust is the main enemy of painting. It absorbs moisture and microorganisms, which can lead to mold. What can I use to clean an oil painting? A soft brush. A wide, soft, natural bristle brush (such as goat or squirrel) works best. Using light strokes, brush away dust from top to bottom. A velvet cloth. A dry, clean microfiber or velvet cloth can be used, but only if the paint does not have a high impasto (brushstrokes) that could snag the cloth.

What I should definitely avoid: Using damp cloths or sponges.

Water can penetrate microcracks in the varnish and damage the base of the canvas. Using household chemicals, alcohol, or soap. This irreversibly dissolves the paint layer.

3. Myths about “folk methods” of care.

The internet often recommends wiping paintings with cut onions, potatoes, or even bread. Forget about it! Organic food residues become the perfect breeding ground for bacteria and fungi, which will eat away at your painting from the inside.

4. Storage and Transportation

If you need to remove a painting from the wall: Store them upright. Do not stack paintings face-to-back, so that the stretcher bar of one does not press into the canvas of the other. Breathable packaging. Use bubble wrap for transportation, but do not leave the painting in it for long periods of time. The canvas needs to breathe.

5. When is restoration necessary?

If you notice that the paint has started to peel, the canvas has sagged, or dark spots have appeared, do not attempt to fix it yourself. Consult a professional restorer. Once every 10–15 years, it is useful to show the painting to a specialist for a preventative inspection and renewal of the protective varnish layer.
