Ammonia is an alkali solvent. Vinegar is an acidic solvent. I’m not sure any solvents are good for wood. The alkali in amonia would dissolve the lignin in wood, but if it encounters oil before it his that it won’t. Flooring Mfg.s say to never use straight ammonia on wood floors, but Adding some ammonia to wood floor cleaner is ok.
I think the guys who use it would know and say something if it were screwing up their stocks. It seems to me the cautions about using amonia on steel are exclusively because it’s anhydrous (a water solution) rather than it reacts on its own. Add alcohol to dry the water quickly, and cutting oil to leave a film once it’s dry and there should be no problem…
