Mix baby powder with rubbing alcohol and apply that in circular motions
Or use fluon

I’ve heard many use olive oil.
I think it’s important to consider what species is being contained. Location can play a role too. Ie if humid and hot environment Vaseline will just run and talcum powder (baby powder?) will get moist and not work.
Applying fluon or Vaseline too thick and/or not wide enough will effect the results as well.
I have also read fluon for example doesn’t stick to silicon.
Check this list out. It might help
