[Closed] best dropper stanchion Lube ?

For my forks I use Fork Juice before and after rides/cleaning. Having just got a new Giant dropper under warranty, due to the first one losing it's anodising after 2 gritty rides, I am keep to do some preventative maintenance.

Online stuff suggests unscrew the collar and apply 'grease', though I do winder it this could be a bit too sticky and attract grit into the seals ? any better suggestions ?
