I'd try wire brush and WD-40.

So the two answers were wire brush & phosphoric acid to remove the
rust, and then WD-40 as a rust preventive.

Speaking of rust preventive, do you generally put WD-40 on your
tools or just those that have been wire brushed?

Or can I substitute motor oil for WD-40 (I never understood WD-40).

I ask because I never oiled tools before also.

Is the oil needed because the wire brush removed a thin layer
of oxide?

Danny,

When ready to oil after cleaning use a clean rag, motor oil -- applied
sparingly thin. The oil prevents further rust, at least until the
next time g I watched my grandfather save his hand saw from the time
I left it in the yard and the dew feel upon it. No belt wippin' that
time ;-|

Don't over think this. Some tools in that tool box you left outside
are not worth keeping.... hack saw blade..
