>>2934951>>2934959please, do not use strong isopropyl on glass and sensor. that will ruin your coatings in the long run. you need to mix it with filtered water or get an already diluted mixture, I use 1:1 and ive heard of others using 1:2 isopropyl to water.
You should also take a moment before hand and see if you can clean the sensor without any liquid at all. use compressed air and stiff lens cleaning paper. only if that doesnt clean the sensor should you try using liquids to clean off the sensor.
