I haven't wet cleaned my d7200 in almost a year. Occasionally I get a spot and either the blower or sensor brush is able to clean it. Every once in while I get something that the sensor brush can't clean so I have to wet clean. Its probably been 4 months since I last used the sensor brush.You may have had a slightly dirty sensor in the past and not noticed. Smaller particles at low f stops might not be visible. If you shoot at the clear blue sky or white ceiling at a very high f stop, you will see any dust at its worst.</blockquote>
