A wire wheel with very, very fine wire, used judiciously, can do good work. The face of the wheel does not touch the work; the side of the wheel is used with a wiping action. The wheel is broken in first. The average hardware store wire wheel will remove rust, and will usually leave a wire wheeled surface.
There is an element of skill required to use a properly prepared, appropriate wire wheel. A lot of harm can be done in a remarkably short period of time, otherwise.
Same goes for the use a Dremel tools.
