Muriatic acid. it can be diluted with water to slow it down a bit. Great stuff!

Why is no one mentioning that the sparkplug is probably compromised now.. If it was that dam rusty. Then the acid may have breached the seal that isolates the electrode 🤔

The part that you need to clean is the electrode and it's still covered with carbon.

ita muriatic acid. it makes people comment and say it's muriatic acid after they read everyone else's comment saying the same thing. but we feel more important when we can feel smart because we said it too.

I see your hands are protected don't ass around and get that stuff in your eyes ! having that type of an effect on metal, this liquid gotta be some form of acid . "a bit of advice tho", just buy yourself another plug...

looks like all bright or alumabrite. Basically hydrochloric acid... it will eat the seal between the ceramic and metal and cause failure... been using that shit in the marine industry for 30 years its not a good idea it removes alot of material
