Default Engine Bay Rust Correction/Repair?

I just purchased a 2005 STi that came from Michigan. All-in-all, the car is in pretty good shape, but the engine bay has some rust/corrosion on some things:

Coolant Res


WG


There's also rust on a lot of bolts, and various brackets.

What is the best way to clean this up?

Thanks.

Try hitting it with steel wool depending on how corroded it is. my coolant tank has some surface rust as well. Then again I'm in Cleveland Ohio...

It's gonna happen on a car that old. You can try CLR+an angle grinder on the res tank...you've got rust by the neck, that's where mine was when it sprang a pinhole leak!

Thanks guys, I think I'm just going to purchase a new coolant res and wg actuator, and replace most of the nuts/bolts. For the rest of the brackets, I'll try cleaning them up with steel wool, grinding and paint.

Thanks for all of the suggestions!

I've thought about this, but I think the rust is pretty bad, almost all the way through in some places. In my experience, rust converter just turns the rust into primer, but I don't really want to paint.
