Ammonx-lo is used instead of dawn, there is the surfactant factor in the mix, usually the lo is for your more steep jobs to minimize the run-off and allow the mix to dwell longer to be more effective, TSP is the kicker in the mix if need be, you need to watch the TSP factor around glass as it will etch it, it ruins glass so doorwalls and those fancy bay/bow windows can catch it if your not careful using it. One more thing is TSP is not always welcome (illegal)in certain states so you need to ck that out.
I think many guys dumped the TSP factor to eliminate risk.

The recipes ( tile/asphalt/metal/etc) are all over the forum and the best advice I can give is get your set-up done and practice with water and some surfactant in the mix to learn how the flow will go with individual tips you might use. Also helps to get some practice in so your not fumbling in the field.

There is so much info and reading through the threads is your best source based on the many experiences compiled from all the guys here.

Best of luck and when you get stuck ask away, someone will answer.

i use about 1/4 gal for a 50 gal mix ... could probably get away using a little less, but it seems like every roof i do is 7/12 minimum, and i've yet to master the art of controlling my runoff

you have to order it from Don at Brainerds, he's in NC ... it's about $70 shipped

hit "ammonyx m" in the search, there's a ton of info, including his contact info
