Bleaches out water stains on wood
I bought this because I have read in many sources that oxallic acid will bleach out the color changes made by water stains on wood.  I have used "Bar tenders Friend" cleanser up until now.  If mixed at the proper proportions this does a great job.  Brush it on and around the effected areas as a paste, let dry and brush off.  You will have to use some water to dilute the residue. Do not let the water stand.  Wipe it up quickly.  I hope you get as good of result as I.
