Rust at the exhaust manifold studs and nuts. Rust has welded where the flange nut meet the manifold. Rust at the manifold to header pipe. And one hanger. The used Cat back from 2015 is done. All welded together. yay.
Recent research suggests the user of either muriatic acid (a dilution of hydrochloric acid to <9) or white vinegar. Eye dropper or toothbrush. Rather vinegar as it is far less reactive.
I understand with Kroil or Zep, as these have a rust dissolving action, it can take days, week, months. Cycle the heat by running the engine.
Have you folks use acid to free them rusty nuts and bolts like in the exhaust?
Please advise.
Thank you.
