What is the best product to use the clean lines our system is really dirt we have flushed with what till clean but feel we should clean it better with something but not sure if this is not a good idea.FYI we started with well water then switch to glycol/water premix 15 years ago.

    Flush out what you have, if it is PG you can flush down the drain

    Run good water to flush all loops

    I would add a cleaner next and run for a day or so. At high temperature if possible 

    Flush again then add new fluid

    Buy premixed glycol or use DI water if you mix your own blend.

    Rhomar, Fernox and others have a single aerosol can of cleaner that you squire in
