How can I cure creaks in a plastic dashboard?

I have in the past cured creaks in dashboards and other internal plastic fittings by giving them a liberal spraying of an aerosol wax polish. Leaving for an hour or so for it to penetrate gaps then polish off, for a clean and hopefully squeak-free dashboard.

Top tip. Thank you. Other readers suggested WD40 and silicone spray.
