Dont use just citric acid. A far better mix is to use 100gm citric, 40gm of washing soda (tesco green bags) and a squirt of fairy liquid per 1L of water.
It is reusable many times. Doesn't turn the metal black. And doesn't etch the metal so much.
It is a similar solution to Evaporust.

Yup exactly those.
When mixing watch out for fizzing - loads of CO2 released.
You can use Caustic soda instead - no fizzing. Just more dodgy to handle.
30gm if using caustic per litre.
Not my invention sadly - bloke on Youtube did all the donkey work. It is actually better than Evaporust.

i was thinking if i cant submerge the whole part (crash bar off a car) would it help to soak an old flannel and rest that on a bit that wont dunk in the bucket? hoping i can each end one at a time
You can try - or make up a paste using something like xantham gum or even flour or wallpaper paste. Let us know how it goes!

worked a treat so far , made some up in a bucket with very warm water and its cleaned it up overnight
is there a preferred way to reheat the mixture , not sure the mrs wants me microwaving it
Why are you heating it? My mix worked fine at about 16C in my warehouse. Only 3 hours for some pretty rusty bolts. Overnight should be fine.

assumed warm = better both for results and the initial mixing of the powder ? ive got to soak the other end so see how it compares in cold water
I wouldn't use warm/ hot water for mixing - it can get a bit violent anyway
Used some of the witches brew Fizzy & I made , it gave fantastic results on a half a galv. bucket of well rusted nuts & bolts left them covered for two days .. they developed a white creamy hard crust in some places . . drained and washed them out. Then put them in a clean cement mixer with a some gravel , sharp sand and some water .. Drained , re washed in clean tap water then rumbled again in gravel & sand . Then air line dried off over a grid and hand finished with a wire brush & some bits of old scrap toweling where needed.
Laid them out on the bench top , they then got a 1/2 cup of WD 40 sprayed over them ,& put back in the bucket , now a month later they are still matt zinc and clean & free turning. The rusted bucket bottom cleaned up too as if well worked /worn zinc & is still like that .
I played again using the same initial batch I'd used for the nuts & bolts , popped half a dozen very old lightly rusted Moore & Wright wood chisels in it . Left them in for four days to see what the effect would be,
Don't leave then in so long , what was immersed has no rust at all ...BUT ..... the steel immersed had considerably darkened and there were oodles of very fine spider web style lines all over the immersed metal , obviously such a long immersion dissolved something in the steel . The darkened steel polished off but the most of the fine web design stayed. They sharpened up OK though

Just to confirm that quantity, its 100g per liter of water for the citric and 40g of soda crystals?

ive gone from being really pleased with the first overnight results to a bit miffed , the last specs wont shift after another 24hrs
ive rattled over then with wire wheel /60 grit , scrubbed with washing up liquid and put a bit more citrus in
