A painting is „low-maintenance“ in itself. It's perfectly sufficient if you dust it occasionally (preferably with a feather duster – not a damp cloth).

I use artist-quality paints that are as durable and lightfast as possible. I also protect the paints with a varnish, a protective layer, so that they remain vibrant for as long as possible. Nevertheless, it is recommended not to choose a location for the picture that is exposed to direct sunlight from the start – so that the colors do not fade. Excessive humidity in the room should also be avoided.
