Abstract:
A process for cleaning an inner surface of an aquarium tank which has at least one curved vertical corner, said aquarium tank having a base, a vertical wall assembly having at least a first flat surface and a second adjacent flat surface surrounding said curved vertical corner, wherein each of said flat surfaces comprises an outer surface and an inner surface and said curved vertical corner having a curved inner surface having a radius of curvature, said process comprising:placing an outer wall magnet-containing handle against an area of said outer surface of said first flat surface of said vertical wall assembly;placing an inner wall magnet-containing cleaner against an area of said inner surface of said first flat surface of said vertical wall assembly, said inner wall magnet-containing cleaner being adjacent to said outer wall magnet-containing handle so that the magnet in said handle attracts the magnet of said inner wall magnet-containing cleaner and said inner wall magnet-containing cleaner having a curved edge having a radius of curvature no more than the radius of curvature of said curved inner surface of said curved vertical corner;moving the outer wall magnet-containing handle along said outer surface of said first flat surface of said vertical wall assembly in a horizontal direction towards said curved vertical corner while moving said inner wall magnet containing cleaner towards the curved inner surface of said curved vertical corner;aligning said curved edge of said inner wall magnet-containing cleaner with the curved inner surface of said curved vertical corner so that the curved edge of said inner wall magnet-containing cleaner touches the curved inner surface of said curved vertical corner;grasping the outer wall magnet-containing handle and moving said outer wall magnet-containing handle in a vertical direction so that the curved edge of said inner wall magnet-containing cleaner rides along the curved inner surface and cleans the curved inner surface of the curved vertical corner of the aquarium tank; andmoving the outer wall magnet-containing handle in a horizontal direction around said curved vertical corner to said second adjacent flat surface of said vertical wall assembly, while moving the inner wall magnet-containing cleaner around the curved inner surface of said curved vertical corner to said inner surface of said second adjacent flat surface of said vertical wall assembly.
