I'm 80% sure I've got iron stains as a "ring" around where the winter water level was (stain happened 2 winters ago, I lived with it all last year as I fought my builder on other possibly related issues.)
Vitamin C held against it under water for a few minutes does seem to lighten it a bit. Now I could do the full AA treatment idea of course.
However, since the stain is completely accessible above the lowered waterline before I open, I was hoping to instead directly treat it somehow. Perhaps with a sponge/brush combo: douse the sponge in AA-saturated water, rub onto the stain, scrub with brush.
Then when I go to open, start with a sequestering agent (Jack's Magic <color?>) as I bring up the pH.
Anyone ever tried this direct-application method, and have recommendations on equipment (sponge-type, or brush type?) and the type of Jack's Magic I should use?
Or - please tell me if i'm stupid and about to create trouble, and I'll just do the full AA after I open before raising pH.
