The short answer is, "DO NOT CLEAN YOUR COINS".
If you have a coin with any collector value to it or, you are hoping to increase the value of a coin by cleaning it, any cleaning process will damage the finish of the coin by introducing tiny scratches or removing small quantities of metal.
Any cleaning process will possibly render the coin worthless at worst.
If you have a coin of no collector value and you would just like to make it look nice and shiny, you could use any of the commercially available jewellery cleaners.

Yes windex can clean a penny, I did a science project on it in 8th grade, and windex cleans pennies better than salt water and vinegar. It cleans a penny because it has ammonia in it which can cause some sort of chemical reaction with the copper which in turn keeps the penny clean
