Think you will find a lot depends on the strength of the phoisphoric acid. Aslo things like milk stone remover may contain other chemicals to assist the removal (of limestone). I have used "Metal cleaner & restorer" by Swafega (a phosphoric acid product) but that can be expensive. B&Q use to stock it but then stoped and had it on clearence dirt cheep but I mised out on the good price! I did manage to get one of the two box packs some timeback (2x 5lts) for for less than what most on ebay are selling just the one 5ltr.You're right, some things you can't unsee!the
I had switched to citric acid and found bying a 25kg bag worked out cheeper than small packs, but as with most things over the last 2 to 3 years prices have shot up. It was something like £40 for 25kg sack now it's £80 plus !
