How do you guys clean and sanitize motor or electrical compartments?

How do you guys clean and sanitize motor or electrical compartments(fully enclosed or partially enclosed) of food industry equipment like a large meat grinder, or silent cutter, or injector? 

Thanks in advance,

I use a sanitizer that evaporates on motor components and everything that comes apart around it gets a 5 step cleaning ..

Here in our bakery we use Alco Spray from Sanimarc
