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

Olive oil is popular with guys and gals who collect ancients. They leave it set for weeks on end. Basically, the coin has been encrusted with dirt and junk for probably hundreds of years, so the coin is probably not going to be MS-xx!!

Thingee, I've only used olive oil, but have read good things about mineral oil. Seems there is less darkening mainly because mineral oil isn't acidic like olive oil.

Maybe on the next batch! (I actually don't clean ancients very often - I usually get a dirty batch every year or so. It's kinda fun - kind of like buying a whole bunch of grab bags)

Also olive oil is said to rot coins.

The olive oil doesn't rot coins, it rots itself(olive oil exposed to air for long periods of time will go rancid)

Estimated soak time is few seconds to minutes. Really depends on how bad your coins are.

And yes, rinse with distilled water and pat dry with a cotton towel.

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 !~!
