Use the age old food service cleaning method Wash Rinse Sanitize.
Get a bucket of soapy water and give them a good scrubbing this will get the grease dust etc. Rinse with clear water to get rid of the soap, then sanitize with a quite diluted solution of bleach. About two hundred parts per million. It is about a cap full per gallon of water. Or in other words the solution will smell mildly of bleach but not be overpowering.
Let the bleach solution air dry.
This is the proven method of cleaning and sanitation for all food service plants, some use quatanery ammonia but many use this bleach method. \\\\
