Swabs come in various sizes. I am using the full-size sensor cleaner, which leaves no extra room in the camera body but does an exceptional job of cleaning -- the best of anything I have tried. Used with the proper solution, sparingly, it cleans all mess, picks up all dust, leaves no streaks or marks, and does not scratch the sensor. Visible Dust offers several similar products (with clear descriptions and comparisons), and users should select carefully what they need. Packaging is bulky, and product is very expensive but absolutely worth it. Also good to have several sizes of swabs (small for touch up, and corners).
It worked just as good as it said it would with out any problems at all [...]
