I researched this a couple years ago and could not find a product that removed these tentacles. You can try soap and water and a scrub brush. I tried that plus scraping with a putty knife. I I could still see the shadow of where the vine had been. It is as if the tentacles embed into structure.

As wings said, there is no magic potion,they need to be mechanically removed( ie,scrapping, sanding, etc)

Science is still trying to find out what adhesive figs use. Scrape, prime and paint is the only way to remove them.
