Bert likes cleaning dirty indoor coils with the aerosol coil cleaner in Refrigeration Technologies’ Viper product line. It comes out of the can with relatively high force, and the foam expands as it settles on the coil, capturing soil as it does so. The aerosol coil cleaner is also a degreaser, making it a solid option for working on restaurant equipment. The Viper line also has an EVAP+ cleaner for evaporator coils, a Heavy Duty formula for condensers and other relatively heavy-soil applications, and a special pan and drain treatment that can replace pan tabs.

The slant coil in this video is quite dirty, but it’s a good candidate for a clean-in-place because it is so accessible. Bert cleans the coil using the Viper aerosol coil cleaner by spraying it from bottom to top in a zigzag formation. The aerosol can sprays the cleaner in a sharp stream that can pinpoint especially soiled areas, all without harmful chemicals, toxic fumes, or the ability to burn your skin. The dirt works its way out of the coil as the cleaner runs down the coil and overlaps with itself.

After some dwell time, Bert uses a soft toilet brush to brush the coils in line with the fins. That’s how he gets the bulk of the soiled cleaner off. Then, he goes back through with a shop vac to suck the rest of the cleaner and soil out from between the fins. Finally, he takes a pump sprayer filled with water and rinses any leftover soil or cleaner off the coil.

Bert finishes off the job with a quick application of Viper EVAP+, which is a self-rinse cleaner. He also applies just a bit of Viper Pan and Drain Treatment to the drain pan.
