I dug my cooking gear out of the shed today and found my BBQ plate has now got some surface rust on it.

It's a good quality steel one that was shiny and smooth when I last saw it.

The rust is bad enough to have scarred the surface of the steel a little.

What's the best way to get rid of the rust and make it good to cook on again?

Thanks for any good advice.

Depends how fussy you are, I guess.

At a National Park fireplace/BBQ that is all rust we don't do so much of what follows. Just heat it up, scrub with oil and newspaper, a water rinse so it sizzles dry, oil and cook.

For my own plate maybe an angle grinder and a flap disk to get rid of embedded rust, then wash and re-season as you would a new plate.

If the rust is just surface rust, not embedded scale, maybe a wire brush (not necessarily powered), wash, heat it and scrub with cooking oil and newspaper until there is no stain on the paper. Then wash again and re-season.

In the camp oven tips I’ve read they mix molasses with water 1:10 and leave it soak for a week. Job done. The results look good.

That works well,
I just soaked a bunch of steel antenna clamps for a fortnight and they come out spotless, nuts freed up on the threads and all.

Yep the molasses or (trade name Mola fus) is great, I have put gears and all sorts of rusty things in a tub of molasses and they come out almost like new, but it does take some time.
We also use molasses at 10:1 on all the fruit trees to increase the microbial contents in the soil.
A friend of mine submerged a whole small lathe ( 750mm long) into molasses tub, and once again it came out like new, but took time.

If it is not a paper thin plate heat it up hot then throw half a bucket of water on it, let it cool a bit, oil it and start cooking us old truck drivers travel light.
