When I took over our current location, I found that the previous occupier did not use his exhaust hood, and because of that, all of the refrigeration had a coating of sticky coagulated grease and large dust bunnies throughout. Even in my walk-in cooler! (I have no idea how he accomplished that spectacular trick)
I use a product made by Davies Chemical named DC-99 to dissolve that nasty coating which I found everywhere. It is not caustic, it does not eat away metals, but melts this grease right off everything. And it doubles as a stripper for vinyl floors. I cut it by 50% or more depending on what I am cleaning. it does a great job on condenser coils with a brush if you have a sticky mess on them like I found. I use it on my grease baffles, pans that go through my BBQ pit, on the sides of the deep fryers, and it makes a great floor cleaner for tile floors.
Side note;
the company that installed the exhaust hood had the MUA fan unit had it wired backwards, so it wasn’t making up lost air, it was also acting as an exhaust fan. So this might explain his reluctance to use the exhaust hood, the first time I turned the hood on, it sucked a window right out of it’s frame! A little fan speed adjustment, and fixing the MUA took care of that.
