Use
this method to remove token from metamask. And it should be noted, this method only excludes this token from appearing in the metamask. If you view your address in explorer or import your address to another wallet, minereum will still be visible. Minereum tokens are not actually removed from your wallet until you send them to another address.
This method is only to delete the token if it has been added to the metamask, if it has not been added then this token is not in the list of tokens in the metamask. I think there is no way to delete every token in explorer other than dumping it on the burn address.
