Can anyone advise on treating corrosion?

It’s come back as an advisory on my truck and I’m a bit skint right now so would like to treat it myself if possible.

if anyone could give recommendations of product and areas to avoid I’d appreciate it.

Dinitrol is good stuff. Use a wire brush to get any loose bits off and then spray dinitrol on.

Avoid the exhaust otherwise it will burn off when you start the car and make a very nasty car.

Nasty smell I mean!
