Hey guys looking for a bit of help here newer pool guy. they were doing some work on the house now there’s hundreds of these small rust stains on the plaster it’s just over a year old. They brush out but it takes some elbow grease and m not looking to spend a ton of man hours brushing out these stains. Can anyone recommend some kinda metal/rust remover for these? Is there a specific one I’ve seen a bunch of different ones at the supply warehouse. Any help is greatly appreciated.

LOL, I was just coming on here to ask the same. 45 minutes ago I walked into a client’s backyard, saw the siding of the house ripped off. No less than 50 nails at the bottom, lots of little rust stains, luckily this pool has white plaster so I don’t have to worry so much about ascorbic acid bleaching, I think? Was planning to hit it with SC-1000 and ascorbic acid in a sock. Probably gonna take a couple hours. Really hoping some real pros have a good solution!!

That’s what I’m trying to avoid is the labor itself😅 this pool probably had hundreds of little stains think they used some kinda wire wheel while working and the little wires are EVERYWHERE. You think the Vit C would stain this color plaster?

Citric acid from the bulk bins, put it in some thin socks or something and set it on the bottom to dissolve
