#stovewash#orthophosphoric#acid If the stove in your car has stopped heating, then in 90% of cases the reason lies in the radiator of the interior heater. Traditionally, aluminum radiators are washed with acid - citric, acetic, lactic, etc. Even Coca-Cola is used! I present to you a very cheap, effective and innovative way of washing the radiator with orthophosphoric acid! Orthophosphoric acid reacts well with deposits that are inside the radiator, as well as oxides, silica, silicates, but does not react with aluminum!
