...until the lubricant dries out
.
Higher end vehicles often use fabric, rather than plastic, for hidden things like the outer cover of the loom, precisely to stop this kind of rattle from developing.
Finding the source and and using felt & cloth to stop the plastic-to plastic contact will get you a permanent cure, but spraying a nylon lubricant is, sadly, only going to give a temporary fix.
For anyone who's bothered by these niggly rattles and is prepared to take the time to isolate the cause & fix it properly, craft stores like Hobbycraft sell all kinds of useful materials - their sheets of self adhesive felt are particularly useful

Which reminds me that it's about time I spent half an hour sorting out a rattling glovebox on the Panda.
