Airspirit at Procooling came up with *sol
*sol (75% Pine Sol 25% Lysol): cleans hose deposits, kills bugs, raises your grandmother from the grave, organizes your socks...
You can mix the *sol mixture up tp 50/50 water and it still works great.. run it for a couple hours "The mixture should be warm"
then flush flush flush with water.. then add your coolant of choice s and your up and running with sparkly newish hoses.
Airspirit collant=70% distilled, 20% red glycol, 5% hyperlube, 5% sanitizer
sanitizer = non cloride non bromide spa sanitizer
I run 99% distilled 1% Humidifier bacteriostat. I think I will add 5% Hyperlube tho..
The *Sol mixture will clean anything but scaling deposits from hard water.. for that you need CLR but be careful with it. if you have any aluminum in your system I recomend not using CLR at all.
*EDIT If you use Water Wetter in your system that probably is causing the "White Stuff" I recomend against Water Wetter in favor of one of the above coolants .02 ;-)
