Thus, fire inspectors throughout the USA and Canada will inspect all commercial kitchen exhaust hood systems to make sure that they are cleaned prior to the grease build up. As long as restaurants cook food, this industry will always exist whether the economy is slow or thriving. Not only is Restaurant Kitchen Exhaust Hood Cleaning a recession proof business and required by ALL restaurants but also the cleaner has to be TRAINED, QUALIFIED AND CERTIFIED!
