If they are like Gen 1 scoops then here's what I remember.
The scoops are cast aluminum alloy that is anodised a grey /silver colour.
If you remove the anodising coat, the Al alloy has blemishes, best described as patches of a slightly different colour.
Anodising is very durable so brake fluid should not have damaged it.
If you plan to do it yourself, then I'd suggest using a paint stripper to remove the clearcoat. Then polish them bearing in mind the anodising coat is thin.
If it goes wrong, you can paint them, have them anodised or powder coated. Or just not look at them.
