Maintenance and lifespan of PDLC

Cleaning and maintaining PDLC glass and film, and how to recognise ageing. Tips for a long lifespan.

Clean with a soft microfibre cloth and water with a mild, neutral detergent. No abrasives, scrapers or aggressive solvents on the film.
Never spray directly along the edges of a film; moisture can attack the busbar and the edges.
Avoid high temperatures (e.g. film directly behind dark glass in full sun) and long UV exposure on unprotected films.
Ageing usually shows first at the edges: a yellowish or dark edge, or small spots that no longer switch.
Do not leave standard PDLC switched on day and night unnecessarily; it saves power and lifespan.
