The best home Lab for a clean sensor. It seems crazy someone would use Post to edit out spots. Some will go as far to replace the actual sensor with a new one. But the real way to do it is this: I know with older DSLR Cameras and Mirrorless with or without Dust Delete clean. That often you clean the sensor with the correct swab. But still have dust spots in your photos especially against bright backgrounds like sky in landscape. So I found a solution for the stuck on spots. As sensor cleaning fluid solutions are fairly weak. And you are really only cleaning the Low Pass Filter on the Sensor. Begin with blowing out camera- with either a Rocket blower (I use compressed air in a can for first blows).Then lock up mirror if DSLR and blow again a safe distance with compressed canned air. So start with boiling water, add to a small container or cup/glass. Then add 1/4 % dish soap to the boiled water. Stir. Now while this is still boiling hot. Use your sensor cleaning swab. Dip it in the soapy hot water. Then swab your sensor as usual. But give it a few extra passes with decent pressure. Re-dip swab if needed. You will obviously see the wet soapy residue on the sensor. Let sit for a minute. Then take a clean swab to dry sensor. Have Q-tips ready if any residue shows as lifted to dab out. Then you will need a cup of clean non soapy boiled water. While still boiling hot, Swab your sensor again with a new swab. After swabbing with clean hot water, Continue now to wipe dry with another swab or 2. After this, you can now swab your sensor again with the sensor cleaning Fluid. Give a drying blow with your rocket blower. Also give your mirror a wipe after unlocking. Final blow. This works on the most stubborn stuck on spots. This method will require many swabs, But 5-7 dry swabs is worth it when you have a pristine clean sensor, and crystal clear photos. Believe me that 212 F boiling water and quality degreasing dish soap like Dawn will lift and remove all spots and contamination. Most professionals don't realize how much of a haze is on their sensors. But this method will bring a scintillating clean sensor, and the colors of your photos will pop. But the camera manufacturers don't want you to know this. As disgruntled photographer will choose to upgrade when not necessary. This method Restores any sensor to a fresh and new state, old or new. As this should be included as routine Maintenance for all sensors, Once a year at least. Giving you an A1 clean sensor, free of haze or sensor fluid contamination from repeated cleanings and general pollution. Don't let Canon and Sony win the battle. A professional want's the pure images the camera was designed for. Not a degraded image haze from daily pollution that sensor cleaning fluid cannot handle. I plan to market my technique very soon with a packaged dish soap formula and instructions on how to mix with 212 F boiling water, and clean a sensor to absolute perfection. Thanks for reading.
