Lockrings are used for cassettes and centerlock brake rotors - both of which are supposed to be torqued to 40 Nm. If you're looking at removing a cassette because the bearing cones need attention, you'll also need a chain whip. And a torque wrench to reassemble it properly. Or you could simply ask your LBS to look after some things.
Cleaning a cassette on the bike, wheither with soap and water or a degreaser, risks removing grease from the wheel bearings, or contaminating them with water, or both. Yeah - some professional mountain bikers use power washers at competitions - they also replace bottom brackets and wheel bearings every year.
