Any gentle degreaser.
Try starting with dishwashing detergent and water.
Coke or sprite will change the color of a penny.
If you can look 'through' it easily, yes it homogenous. Most of them are! If not a 'clear' fluid then it is heterogenous.
Small drops of liquids tend to be spherical because of their surfacetension. Surface tension is the result of intermolecular attractingforces. When you put a small drop of a liquid on a solid surface, theinermolecular forces of the solid surface will tend to attract the liquidmolecules. Depending on the magnitude of the different forces, the solidsurface will present certain degree of 'wettability'. If you compare howa drop of water sits on a clean penny and on a penny that you rubbedwith your fingers, you'll notice that the drops contact angle differ.The drop on the clean penny will cover more contact area (more wettablesurface) than the drop on the 'oily' penny (less wettable surface). Oilreppels water because the intermolecular forces between the water andoil molecules are very weak compared to the intermolecular forces betweensimilar molecules.Now, water intermolecular forces are paricularly strong, and so the dropof water on the penny will resist more than the oil molecules to be spreadedon the surface of the penny. Oil drops tend to wet more the surface of thepenny and will tend to occupy more area. And so you'l get fewer oil dropson the penny's surface.

Salsa is a liquid because it is a saucy mixture typically made with tomato, chili peppers, onions, and other ingredients that are blended together to create a semi-fluid, pourable consistency.

depending on the seriousness of the collector, I have seen a clean unscratched coin of its kind sell for $20.00 cdn. I was the the collector who bought it but the history of it was priceless! VK Vancouver, British Columbia
