First field test. Dust courtesy of previous owner I guess.
A more recent shot. After repeated Rocket Blower sessions. Less dust but unfortunately new stains, likely pollen, that the Blower cant remove. Consider wet "Eclipse" swabbing.
Started out with a sensor brush. Not bad, but it did smudge some of the larger stains.
First ever swabbing with wand and Eclipse E2. Not quite there yet.
Second round of swabbing. Actually made it worse.
Third attempt. Smudge will likely not show up in real life so I'm going with this for the moment.
