Ajax, the cleanser.

Ajax is a cleanser. They have the motto "Stronger Than Grease" which is an allusion to Ajax's strength and him being stronger than "Greece".
It could also be that the cleanser was named after Ajax because he never needed aid in battle. This could be implying that Ajax, the cleanser, doesn't need aid from any other cleanser.
