Abstract
A process for using a magnetic aquarium tank wall cleaning tool for cleaning the inner surface of an aquarium having one or more curved interior vertical corners. Magnetic cleaners for aquariums eliminate the need for reaching into the tank or manipulating a cleaner with a long handle. The magnetic tank wall cleaning tool has at least one edge which is curved. The radius of curvature is no more than the radius of curvature of the inner surface of the tank to be cleaned. The cleaner can be manipulated from one flat surface around a curved interior corner by moving the handle horizontally around the corner.
