suggestions for stain removal while pool is empty

[old_and_busted]

I'm planning on coping and tile in August. The pool will be dry for 7-14 days while this work is done.

I have some copper staining and organic staining from a previous owner. What products/chemicals might I try on stains while the plaster is dry that won't be as destructive as an acid wash but have a chance of working?

My pool finish is white plaster, it's very old, perhaps original 1963 plaster-- but it's only rough in one spot in the shallow end, so I have no plans on replastering at this time just for stains.

Thanks in advance!

I do not do metals but I know this should help

I would do an AA treatment before you empty the pool and once all the stains lift then empty it

Copper stains need a sulfamic acid treatment and then drain the pool. The organic stains can be dealt with by maintaining elevated FC levels for a time and brushing the areas.

See, this is why I do not do metals... Sorry about that
