Wi | Auto antifreeze is almost all Ethylene Glycol based and has many additives that plug up the heat exchangers in plumbing systems. Plumbing and RV antifreeze are generally Propylene Glycol based due to it being less toxic and generally "food safe". Since its used to winterize houses and RV's where people will possibly consume the water. It is good for preventing freezing but automotive antifreeze is better at preventing overheating.
Generally RV antifreeze is what we always use for the sprayer although windsheild washer fluid can be purchased a little cheaper. | |
