Backticks are only used, and useful , when you have 'dangerous' characters
or reserved names in the identifiers names.
I don't think single quotes even work.
And also you don't need to use the PASSWORD keyword in the grant statement.

The clean way:

to know which accounts you have issue:

     select user,host from mysql.user

then SHOW grants for 'user'@'host' for all of them

then revoke each and every grant. (not the GRANT USAGE, not needed, this is
actually just the user account)

if you just want to remove the users as well then use DROP 'user'@'host'


Dirty way:

do it the clean way!

delete from user and host table all the users but the 'root'


Cheers
