Went into Aldi and the standard coke was 2.49 for 2L. But they had a thing called Cola which was 59c for 2L. Compared ingredients and both contained phosphoric acid which I suspect is the main cleaning agent. Other ingredients very similar too. The cola had citric acid which I didn't see in the coke.
Anyway bought 12L total and 2 bottles went down each of the 3 plug holes. Drove an hour after and will leave it in there for a couple of days before emptying.
Considering phosphoric acid is used in rust remover and brick cleaning, and citric is used in limescale remover.
