Has any a solution to these blocking up ? I have flushed the tank and lines with clean water , yet even with a new pair they begin to clog up after a few weeks. I have soaked a spare set in vinegar then again rinsed out , but again after a few weeks I need to repeat the process. I dont know how often I can do this before the elasticity of the clip give and breaks. As a thought I had considered using something like CLR to clean the system, good or bad idea?
As a note the rear washer has never blocked.
