How to Use Corner Swabs for Sensor Edges

Quick answer

Use corner swabs designed for sensor edges, such as the VisibleDust Ultra MXD-100 Green or DHAP Orange, with a single swab per cleaning, working from the center outward to avoid pushing debris into corners.

Step-by-step guide to cleaning sensor edges with corner swabs

1. Prepare your workspace and tools: Ensure your camera is on a stable surface with the sensor exposed. Have your corner swabs and compatible cleaning solution ready. For DHAP Orange swabs, use only VDust Plus. For Ultra MXD-100 Green swabs, any VisibleDust liquid works. Common mistake: using the wrong solution for DHAP Orange swabs can damage the sensor or leave residue.
2. Apply cleaning solution to the swab: Put one or two drops of cleaning solution onto the swab tip. Do not oversaturate; the swab should be damp, not wet. For corner swabs, focus the solution on the pointed edge to target corners. Checkpoint: too much liquid can drip into the camera body or leave streaks on the sensor.
3. Clean the sensor from center to edge: Start at the center of the sensor and gently wipe outward toward the corners in one smooth motion. Use the corner swab's pointed tip to reach the sensor edges. Do not press hard; let the swab do the work. Common mistake: pressing too hard can push debris into the corners or scratch the sensor. Use light, even pressure.
4. Use a fresh side for each pass: After one pass, rotate the swab to use the clean side for the next corner. Do not reuse a side that has touched the sensor. One swab is enough for one cleaning session; discard after use. Checkpoint: reusing a dirty side can redeposit debris onto the sensor, defeating the purpose.
5. Inspect and repeat if necessary: After cleaning, inspect the sensor with a loupe or by taking a test shot at a small aperture. If debris remains in corners, repeat the process with a fresh swab. Do not attempt to clean multiple times with the same swab. Common mistake: skipping the inspection step can leave debris that shows up in photos, especially at small apertures.
