    Viper is recommended for micro channel and if I was going to use something that is what it would be. It seems to be the safest.

    Most sites I'm on, roofs drain into the same drains that storm drain into, or in the parking lot.

    Yeah and that water from the parking lot ends up in rivers, streams, oceans or at least in retention ponds and then absorbed into the ground unless it overflows.

    Years ago I had an employer that wanted us to start using Simple Green because it was biodegradable and EPA approved. Don't have a clue if they can still make that EPA claim, but it is/was supposed to be a 'safer' cleaner for the environment.

    Problem is I hated the smell of that stuff.

    I do a triple evac with nitro to remove non condensables.

    Yes, simple green was only used on micro channels or the Johnstone micro channel cleaner with the power washer 18” or more away..

    I was using Cal-Clean for the past several years, but only when there was oil to be cleaned off. If no oil, then water only. Recently switched to Cal Green because it is approved for the micro channel coils. Only used it a couple of times so far, but seemed to cut the oil just fine.

    That is such a bad idea to drain buildings storm drains, and roof drains into the ocean, and rivers.

    I'm guessing the sewer drains drain into the ground as well.?

    NuCalgon CalClean was what I specified for coil cleaning beyond brushing and blowing out coils.
    Very safe on membrane roofs when mixed as directed. No rinse required.

    in my state all sewer/contained runoff water into sewers, it treated before being released according to their standards, acres of sludge tanks/field tanks then filtered after the heavy stuff settles, methane is also captured and used for fuel, like they do in landfills.. farmers also capture methane to use for fuel, lots of videos are online about it, especially big city treatment plants....

    Yeah, cows with methane collection bags just roam the streets where I live.

    Enter into a Googler:

    Cow methane collection bag.

    There is sanitary system that toilets sinks and etc are connected to and separate storm sewer systems which parking lots and the like never make it to treatment plants. The cost to treat storm water runoff would be ridiculous. This is why it is illegal to connect roof drains to the buildings drain system as some residential and maybe commercial properties did years ago. In my area storm drains are marked stating Do Not Dump Runs Into River, Stream

    Municipalities don't want Street and Roof drainage going into the waste system. Way too much flow during storms.
