I currently clean residential and commercial air ducts and would like to expand my work to include kitchen exhaust cleaning. I would like to help someone who cleans restaurant hoods and ducts without pay, just for the experience. I've studied Delco's videos, the IKECA exhaust cleaning procedures, and researched the internet considerably, so I'm aware of the grime. Also, I'm no stranger to hard work, and would more than carry my own weight. If you're interested in cleaning air ducts, this could be a double blessing. I'm hoping to find someone within a few hundred miles of south-central Tennessee (Petersburg). Thanks for your time. zkunkle@earthlink.net Zeke Kunkle.
