I have the cleaning swabs for my Sony A7II ordered me, because I had found larger grains of dust on the sensor during an event and tried this wegzupusten (had no bellows at hand). It came as it had come, instead of grains of dust were now small droplets of saliva on the sensor ... As is so often the stupidity was punished, in this case the purchase price of VisibleDust swab. I was not quite sure if the orange line is the right one for me, because this is indeed designed for oil spills. But it has helped effectively and reliably even against my dirt. Although the spots were not for a time wipe away back and forth, but only after I've wiped carefully in the appropriate places, but when they were gone, the sensor was clean and clear. The price is absolutely disproportionate, but if you want to take any risks with other "home remedies", a not many alternatives remain. And as the price and the amount on the purchase were known, I can pull this no star and forgive the full credit, since the cleaning performance was great!
