I have some oak parquet flooring that had some water soak onto it and it
caused some dark stains in some areas. I seem to recollect reading at some
time a remedy involving bleach(? maybe) and somehow soaking it, but I do not
remember the exact formula or process.

Does anyone happen to remember this fix?

TIA.

oxalic acid, not bleach. you can get it in home depot in the paint
department, or it is the main (only?) ingrediant in barkeepers friend, a
cleaning supply.
