with some kind of an acid based solvent
lemon juice, because it has antioxidense!>*^#$
An air freshener is and alkali and it does kind of clean.
Lemon or Lime juice I'd imagine. It's a fact though that coca cola has an amazing ability to strip the dirt off of pennies

Depends what kind of acid, and what it spilled onto. - you haven't told us either one.
well add juice to the penny
well if this was for a science experiment then i would say use many different juices such as apple, orange, lemon, lime, also these two are not juices but are good for the experiment vinegar and salt , and pickle juice
Cleaning PenniesUse copper polish if you want them shiny. Be gentle on pennies minted after 1983, though; they're copper-plated zinc, so rough polishing could remove the copper plating entirely. You should know that you should never clean coins that may have collectible value. Even though the cleaning makes them look "shinier," such cleaning removes most or all collectible value. As strange as it may seem to those who aren't numismatists, brown or "toned" coins can be more valuable, because cleaning removes some of the original material, and can leave marks that look bad under standard 10x magnification.I have seen coins cleaned with many household items and experimented with some myself. In one collection I purchased, the collector had even made notes of what he had cleaned various coins with and when. Although several different products will produce a bright coin, in almost every case within a few months or years the coin will look worse than it did before the cleaning.Don't clean a penny unless your a expert at cleaning pennies. I did it when I was 10 and they still look awful. So take my advice. They will look better if you don't do it. Good luck on everything.
If you are going to clean the pool the best thing to do is hire a high presure sprayer.
