I am about to drain the first phase of an ARX cycle, and wondering if I should get a sample and have it analysed. Would the UOA give skewed results due to the cleaning?
The results can be interpeted even with the Auto-Rx in it. But unless you did a before UOA, you won't have a trend. Personally save the money and do a UOA on your first run after the rinse cycle. JMO
