Hello Marcooooo,
We don't have any recommended kits to suggest unfortunately. You can try to do a manual sensor cleaning on the camera. Dust can be removed manually with a commercially-available blower. Before cleaning the sensor, detach the lens from the camera. The image sensor is extremely delicate. Use a plain blower without any brush attached. A brush can scratch the sensor. Do not insert the blower tip inside the camera beyond the lens mount. Never use pressurized air or gas to clean the sensor. Pressurized air may damage the sensor, and sprayed gas may freeze on the sensor and scratch it. If the sensor needs to be cleaned directly, you may want to consider having it done by a Canon Service Center.
