It's a very common technique with tool & car restorers - there's a lot out there about it. Dri Pak, who make the familiar green Soda Crystals packs you get in the UK, have a small page about it: https://www.dri-pak.co.uk/helping-restor...omponents/
I mostly use phosphoric acid which is really cheap to buy in bulk - a lot of the commercial rust-converter products are actually phosphoric acid in a carrier medium (maybe a gel to help it stick to vertical surfaces etc.)
I use both techniques prior to using a Zn plating line - current car restoration is an old Landrover 90 - well known for its rust issues...
Phosphoric acid is good stuff!
