Quoted from YeOldPinPlayer:I disagree. Acids and bases will always neutralize one another. That's the way the chemistry works. The stronger your acid the more abundant the hydronium ions. The stronger the base the more abundant the hydroxide ions.
Vinegar (pH about 3) has fewer available hydronium ions than Zep (pH about 1) so it will take more vinegar to neutralize the same amount of alkaline. It will still get the job done from a chemistry standpoint.
terryb goes into other advantages/disadvantages in his guide.
Once you have used a stronger acid you will realize vinegar isn't doing much besides getting the corroded board wet.
