One of the best things about premium wall art is how little care it needs. But "little" isn't "none", and a few simple habits keep a piece looking sharp for years.
Cleaning
Dust with a soft, dry microfibre cloth every few weeks. For fingerprints, lightly dampen the cloth with plain water. Avoid glass cleaners, chemicals and abrasive pads.
Placement
The film protects against fading, but long hours of harsh direct sunlight are best avoided. Keep pieces away from direct steam, for example right above a stove or inside a shower area.
Hanging and handling
Use wall anchors suited to your wall (brick, concrete or drywall), and lift the piece with both hands from the sides rather than from the top edge.
