After 2½ years of use, my Canon T5 needed a sensor cleaning. Did the Rocket Blower and sensor brush thing, but I still had three (3) tough spots to remove.I purchased this wet sensor cleaning kit as part of my maintenance routine. Read the enclosed instructions, watched a number of Youtube videos and decided to go for it. It turned out to be far easier than you think.You will use two swabs for each sensor cleaning. Starting at the bottom, across the face of the sensor and then back. Second swab across the top. The swabs are not 100% of the width of the sensor. After two passes, my sensor with 3 hard to clean spots was clean.You will be hard pressed to get it 100% clean, since you are not in a perfectly controlled, air filtered room that is totally dust free. This kit will remove the biggest spots and I hope the next time I clean it, I can remove any possible residual that I was unable to do so in the initial cleaning. My test shots looked real good and the big blobs of dust/debris were history!Just be careful, read the directions and watch some DIY videos on Youtube. You will become a sensor cleaning guru after the first cleaning.
