hum, what if ya don't have a dishwasher? like me. though i'd bet there aren't to many folks these days w/o a elec. dishwasher.
anyways. i've been cleaning my fa w/o a dishwaher for years.
break kleen followed by compressed air.... it always makes short work for cleaning the fa. it's so fast i clean my fa multipule times a season.... i know the leo's like to bust folks for dirty fa's... + it's a good thing to do having a clean fa... just makes sense to give yer engine as much fresh, clean air as possible...
