When should I have a painting professionally cleaned?
First, find out how much the painting is worth. Is the price of cleaning by a professional higher than the value of the painting? Then it is worth cleaning the painting yourself.
For particularly valuable (whether tangible or intangible) or delicate paintings, you should hire a restorer to clean them. The same applies if you notice during painting cleaning that the paint is peeling off or cracks appear.
How often should I clean my paintings?
You should remove dirt and dust from your paintings about twice a year. You only need to replace the varnish if the painting yellows or the varnish dissolves on its own.
So that the painting is sufficiently protected from contamination and yellowing, you can also protect it with a glass pane. Especially for high-quality paintings, museum glass is recommended. It not only protects against UV radiation but also reduces light reflection and ensures color fastness.
