going through the exact same thing - engine is out - want to clean and paint underneath it.
Any recommendations on not-too-toxic cleaners, that would remove 30 years of grease and grime, and not damage the fiberglass, before I sand lightly and paint?
The engine area runs under a fake floor, to the main bildge, which is a greasy mess as well.
I was thinking of an orange / citris based cleaner, as the orange hand cleaners remove bike grease, etc quite well. Possible a spay bottle type, from an industrial supplier??
