Like many, I started with the simple rocket blower then after 100s of lens changes and Imatest blemish detect showing me it was time to wet clean I bought Eclipse Sensor Swabs.
Despite using several to try to clean there were two problems- left fibers and smearing.
Out of frustration I called the guys at Lens Rentals and asked what they were doing these days.
They told me Dust Aid and Dust Wand. I ordered last week and the stuff came today.
You'll need a magnifying glass to read the instructions.
Used the blower first, then a wet pass with the wand and a new dry cloth with the wand. Then used the Dust Aid to pick up any debris. Close examination with a loupe showed no dust, no smears, no residue. Imatest confirmed that.
How about a link to where you got it. I don't think I've heard of it, and it's getting close to when I probably need to order something. I have one sensor swab left.
I have Amazon Prime but chose to buy it directly from the Dust Aid website. It was $60 for both kits. Not being able to get the sensor clean was really a pain.
Just did some Imatests. The clean sensor is giving results 20% higher than before.
