Depends how thick the rust is and how thick the sheet is?
I would use an angle grinder with a cup type wire brush - or a flap disk. Be warned - I have burnt out an angle grinder doing that - it puts a lot of load on it!
I have done 2 big welding tables like that. Takes a while - wear a mask - and do it outside

sand blast......there's always some firm locally....if ur not in a rush it'll be beer money.....
My ol mate would have charged a tenner for that size and it would get a decent primer coat as well....
He's now in Ozz.....lucky lad....

This is by far the best option if possible

Build some shuttering and line with plastic, pour in some acetic acid, space plate off plastic by a quarter of an inch, soak for a few days, flip, repeat.
That is why I asked about thickness. Not good on thin sheet. Also depends on what surface finish he wants.
Not always. Thin sheet will warp and surface finish may not be acceptable.
What condition was it in before the surface rust? After a few years outside, I'd expect a fair bit of pitting - is that acceptable as long as it's clean?
If so, acid bath or blasting sounds like the best method, though both will leave a dull finish, blasting more so

If I was going to do a biggish sheet like that, I'd try a petrol strimmer with a wire wheel.
Obviously super dangerous since they're designed for pavement weeds etc. but you'll be the length of the strimmer away from the action.

that's got to be the daftest idea of the day

Why? It would probably work
I have one for doing weeds and paving slabs.
I doubt you would get enough pressure down on it though.
I have seen those and I can imagine how goosed your arms would be trying to control a rotary wheel held a metre from your body. It's hard enough to use one on a 9" grinder.
Not to mention the stress it would put on the strimmer drive train.
They really aren't that bad. Mind you I have a big brush cutter with a harness and cow horn handles.
