The head well i cant say there is a easy way to clean them the fins are a bugger, but the combustion chamber is easy i use a Dremel to polish that..I start with a wire brush on a drill and degreaser, and use the wire brush on the hole head not to hard as to mark the head just get the thick oil and gunk off... Mini steel wool the little soap ones i use them with water they work good, and i find heavy duty green scourers work good in the fins and i use them dry no water.. hope that helps...there are two things on a mower i dont like cleaning they are the head and barrel i dont own a bead blaster or anything like that....Cheers
