Wet cleaning a d600 with sensor swabs easy as pie

Thanks for your reply. I suspected as much. Short answer is you scratch it you fix it. Has anyone had a claim against a sensor cleaning company where the company has paid for the damage? I do not have links at the moment but I have read posts here from people who have scratched the filter cleaning the sensor so I wonder if they had any success with the "guarantee". I have simply used a blower in the past and never needed to do a wet cleaning so I'm a little concerned.
