Now that you have it nicely cleaned, there are a few things you can do:
Coat the cleaned item with a heavy coat of furniture wax or clear spray lacquer before re-installing.
Encourage/impose the: "Gentlemen, please be seated" policy among the males using the facilities.
Post the, "We aim to please. You aim too, please!" sign
Or, if you have a bunch of Star Wars fans among the lads:

Trust me, none of this will automatically revoke their "Man Cards," but will reduce the cleaning effort immensely!
Alternatively, assign them to do the cleaning...
