I have a Mark VII Proflier, I can not keep the presoak nozzles and strainers from clogging. Saturday they were so clogged nothing would spray out of the front nozzles. I have tried Warsaw chemicals and they clogged with a reddish goo, I am now using Simoniz and they clog with a white powdery substance. I have purged the lines and they clog within 2 days. They get so clogged it's difficult to remove the strainers. I have a strainer on the water inlet before the presoak pump and that's perfectly clean. It seems to be once the chemical and water mix after the presoak solenoid. Need help, driving me nuts!!
