Iron stain

#1
So my opening didn't go perfect, or should I say my closing. When I pulled the cover off I found a lonely screwdriver sitting on the bottom of the pool, right under my skimmer. :confused: By the looks of the tool and vinyl liner, it was there for more than a couple of hours. So now I have this "nice" brown stain on the liner. :(

I guess the easy part is that I know that it is an iron stain. Now to get it off of there.

I found the article on metal stains and the Vitamin C / Ascorbic Acid Treatment for staining but those seem to be written to help if I have general staining, not one particular spot to treat. I get that Vitamin C / Ascorbic Acid will remove the stain, but I'm uncertain what to do next.

The stain is about 3" long and 1/2" wide. I've vacuumed up the loose bits.

How much Vit C / AA is needed?
Tablets or crushed in a sock?
Since this is only a spot treatment, I assume the FC drop isn't necessary?
Is the sequesterant needed with this (minimal?) stain?
Once the stain is gone off the liner do I need to do anything else?
Is this amount of staining significant enough in 12k gallons to cause me any future problems?

I'll try to grab a pic tonight.

I would crush up tablets in a sock and use it scrub the stain away. No need for a sequestrant. It should be fine.

Welcome to the forum:wave:

How much Vit C / AA is needed? Maybe 1/4 cup. enough to cover the stain

Tablets or crushed in a sock? crush the vitamions and put them in a sock
Since this is only a spot treatment, I assume the FC drop isn't necessary? correct
Is the sequesterant needed with this (minimal?) stain? No
Once the stain is gone off the liner do I need to do anything else? No
Is this amount of staining significant enough in 12k gallons to cause me any future problems?No

Well, that doesn't look like an iron stain to me but I think trying the vitamin C is still your first step.

Please reread my original post.

I fished this hunk of plastic & iron out myself with disappoint on my face :mad:. I wiped the rusty sludge off the screwdriver and there was a brown stain on the liner under it. It's definitely an iron stain. I think I'm going to wait til the water warms up a bit, it was a balmy 64F this morning. Thanks for the info about the Vit C.
