I want to clean the complete engine bay on my '54 Manhattan, but I don't want to use the foam cleaners that require pressure wash. Has anyone used the waterless cleaners that only require a leaf blower to blow off the residue, such as Sonax from the Chemical guys? Did it work? As I live in a condo, I'm also concerned with making as little a mess as possible. Waterless cleaners would also save the job of wrapping the generator, distributor, voltage regulator, etc in plastic for protection.
