I use acetic acid (vinegar) to clean alkaline battery residue and baking soda in solution to clean acid battery residue.
I have a wash bottle of both on the work bench.
I follow this up by flooding the area with distilled water with the board angled such that the contaminated area is closest to the bottom.
This is followed by cleaning the area with IPA then warming with a hot air gun.
Ensure that you neutralize any residue that has made its way into vias.
If the board is multi layer and the residue has gotten into the inner layers, the board may take heroic efforts to salvage it.

Did someone here suggest Ammonia (Ammonium Hydroxide solution, Washing Ammonia) as a way of removing the crud from failed alkaline battery corrosion?
