It is. All half dollars made in 1964 and earlier are 90% silver.

No, you do not clean coins. Cleaning coins will only damage their value. If you feel you must clean a coin, take it to a coin dealer and see what he recommends to clean the coin, however, they will recommend you not to clean it. Coins potentially worth hundreds of dollars have been brought down to selling them for scrap because people have cleaned them! Do not clean coins!
