What's the general consensus around here about using a small resi-grade steam cleaner to clean evap coils? Is there a consensus?
I've never done it on an in-place coil, but the Boss seems to think it's a good idea. (The idea is to avoid pulling filthy coils whenever possible) As far as I know, the steamer is only rated to produce steam at around 220F or slightly less. Not sure about the PSI, but it's negligible. I used it to clean out my fridge and had to hold the nozzle in place for a while to remove what I assumed was sticky soda residue.
It's a distilled-water cleaner, no chemicals or anything. I tried it on an old slant coil that was waiting to be recycled, using a soft nylon brush attachment, and I have to say it cleaned the crud off better than anything I've ever seen. Obviously I don't know if it damaged the coil in any way, but superficially, at least, it seems fine. Bright and shiny, almost like new. Shame it has a fist-sized hole through the middle.
So... Ideas? Thoughts? Swear words?
