Assuming the coins were taken from circulation, they have essentially no collector value so this is one of the few situations where cleaning won't hurt a coin's worth. You might try some mild dish detergent - e.g. Ivory or Dawn - and some lukewarm water along with a soft cloth.
If the coins are uncirculated or proof, don't try to clean them because these are worth more than a quarter each, and any attempt at cleaning may reduce that value.
