Basically both alcohol and bleach will destroy that area of finish. You can’t clean a finish that has been blotched in this way. You need to refinish.

Take a picture? White stain may be superficial and repairable bit a pic would be helpful.

Probably was finished with shellac so should be able to tint some shellac and redo the bleached spot. 40% alcohol would have no effect on poly or lacquer.

You should try to determine the finish type. If it is an older piece it could be shellac, but, could be Lacquer. Take a Q-tip or the corner of a rag soaked with denatured alcohol and apply it to a spot on the piece somewhere that will not be noticeable, like the back side of the leg, and see if the finish gets tacky if so then the finish is likely to be shellac, if not try the same procedure with a Q-tip or the corner of a rag soaked with lacquer thinner, if the finish becomes tack to the touch then it is likely Lacquer.

This should give you a better chance of determining which way to go.
