I have a Dashcam on the windscreen and a SatNav on a smooth plastic

Both are held in place by suckers, as is usual.

However, they both have a tendency, particularly in hot weather, it
seems to me, to lose their 'suck' and fall off at inopertune moments.

I was wondering if some kind of grease or oil on the sucker, instead of
the usual saliva, would provide a permanent (ideally) solution or, at
least, a longer life than at present.

I don't even use saliva. I do clean it all first with some IPA.
