Sticky, Oily, Goo'y Stuff On Pennies In Rolls

I read somewhere that ketchup works good for cleaning grime off of pennies anyone ever try this or recommend this?

Regardless of what substance you use to attempt to clean anything off a coin, remember this. If the product your going to use is made with a manufacturing process, such as Olive Oil, all manufacturers have different methods and may/may not add other substances to their processes. This means that what may work for some may ruin your coins. The reason is not all items manufactured are the same. Proprietary information is so that a process or finished process may not be immitated.
Putting any oil on a coin to remove another oil is rather on the not to smart side. Putting any substance that contains any acetic properites such as Vinegar, 4% Acetic Acid, is also on the not to smart side of things to do in your spare time. Listening to people that attempted to use wierd things to clean coins, tomato juice, is also on the not to smart side.
If there is not a complete discription of the contents of any substance on the container that holds it, consider yourself just gussing at the results. By complete I mean the exact proportions of all substances within that compound.
A great example is Finger Nail Polish Remover. READ THE LABLE. Many ingrediants are listed but no proportions.

PEOPLE SHOULD NOT EAT ICE CREAM WHILE ROLLING PENNIES !~!
