Is it a physical scratch or a line seen in the VF , LV and image files? Is it perfectly straight or rough looking with little jogs? Unless you mixed a little diamond dust in the cleaning solution( Isopropanol) it hard to imagine cleaning would scratch an AA filter. If it is a pretty straight but not perfectly straight line it could be a streak much like using a squeegy for cleaning a window and lines appear at the end of the squeegy line of travel. If it is perfectly straight and the line in a image is black and uniform width it could be a dead vertical column date line. Each photo-site is read buy addressing a pixel by its row and column. All the cell in a vertical column connected together and each row, all the of pixels on that row are connected together. Any individual pixel is addressed by looking at the row and column information for that pixel, where the row and column intersect, the data for that one cell is read. So is all the pixels in a column are dead( a scratch would not result in no light on that column being detected but would be diffused)it is usually the address line for that column that would have nothing to do with cleaning, just a fluke of a microscopic transistor failing.
