I am using the one from Mckenic instead and I spray on the fancoil, let it penetrate into the fancoil then use the industry type of blower to blow through the coil, it will clear through the dirt onto the other side. It is cost saving in the long run and no waiting time to arrange for servicing schedule.

The spray oni clean the surface only 15%... only chemical overhaul can do the cleaning job 99%...
