The 4 x 4 inch (10 cm.sq.) wipes are perfect for cleaning 35mm and other small areas PEC*PAD is not recommended for cleaning the CCD. It is not the same material used in the Sensor Swabs. PSI does not approve or warranty the CCD or any camera part from any damage caused by using non approved products
