Our cleaning process uses top of the line chemicals and equipment with hard, through work. We use only 3500 psi,. 200 degree hot water, pressure wash. Hoods will be wiped dry, shined with a stainless steel cleaner/polish to ensure that brand new look. A sticker of completion is left upon the hood after all cleaning to show that it is done according to NFPA 96 standards. Along with our "Satisfaction Guarantee" a series of preemptive courtesy calls and post follow-up calls are made to keep your satisfaction guaranteed!
