Olympus Europe recently teamed up with "extreme photographer" Fernando Marmolejo to create an in-depth tutorial that shows you how to properly deep-clean and disinfect both a weather sealed and a non-weather sealed camera body—in this case, three Olympus OM-D cameras.
The comic (or is it sadistic...) minds over at DPReview TV have put together a lens cleaning guide that somehow manages to be three things at once: informative, comical, and extremely painful to watch.
Although cracking open your smartphone and possibly voiding the warranty is never a pleasant task, sometimes it's necessary. For example, YouTube handyman JerryRigEverything's friend recently dropped his iPhone 5 and started getting some serious dust buildup on his front and rear cameras.
In the above video, Jerry shows you how he opens up his friend's iPhone and performs a quick cleaning job on both cameras to get them shooting good as new. (Note: If you choose to try this at home, you do so at your own risk)
