Hi, I just bought the eviteo-clear blower from a shop. After I use it on my lens and my dslr sensor, I use LED torch to check for dust, I realise my lens and my sensor and the mirror is covered with dust with sticky oil substance! I have hard time cleaning up the lens. I dun dare to touch my sensor. What should I do now? Gonna go back to the shop and ask for refund and go to sony service centre to clean for me. Will the service centre clear up for me? The inner sensor compartment is fill with the dust and sticky oil substance.
