Barnacle Buster cleaner

[eze2bme]

Has anyone used the Barnacle Buster cleaning solution in their AC cooling system? If so, did you dilute it or just use it straight from the one gallon jug? The labeling says nothing about diluting it.
Also, it says to run the solution through the system for 2-6 hours. - Did you do that too?
Thanks in advance.

I use Rydlyme. Similar to Barnacle buster but not as pricey. I used at full strength. You can watch the return flow to tell how long it needs to run. The product works well and is much easier to use than muratic acid.

Overpriced acid. Use phosphoric acid. It is not volatile and will not cause unpainted metal in the ER to rust.
