From my experience, clashing metal together works pretty well if you do it rapidly enough. Weirdly, supercharging a jukebox doesn't do anything to them.

when i supercharged a jukebox it work it just has to be close really close

a firework i tested it

slamming a bell repetitively also worked for me

you can also use fire

maybe a nuke will?

you can slam a spike on the ground over and over again it comes off

nuke legit does nothing to it lol
at ALL it just heals the dmg

either setting it on fire or you can get a android and slam it against the floor super fast or anything else that creates sound or heat. That heat generator thing does not work if it does not have enough heat so i recommend anything with fire.

grab a bell and slam it

Use the fire ability, it will take the symbiote off.
