imclean is an IRAF script that displays a set of IRAC images specified by the user. One can then select an individual image and correct artifacts such as muxbleed, column pulldown, banding, and striping. One can also mask out regions so that they are not included in the final mosaics. The corrections can be applied to subsections of the image, or the entire image, depending on which interactive commands are selected. This software works on both cryogenic and warm IRAC data.

This software has been tested on Linux. It should work on other systems where one can recompile C programs and run IRAF.
