Why is an Ultrasonic Cleaner a Bad Alternative to Swab-its?

Ultrasonic cleaners aren't time effective. After removing a zeroed scope and breaking down your firearm to just metal components, your hands will be filthy. You then drop the parts into an ultrasonic tank and turn it on. After one minute, you’ll have clean parts but any bluing or paint on your gun may also be gone. Once you pull all the parts out and put the gun together, you’ll still have to oil each and every part you dropped in the ultrasonic cleaner. Re-oiling is critical and must happen in order to protect the metal components and reduce the wear and tear on your firearm. But that isn’t the only catch. Ultrasonic cleaners use vibrations to shake the metal free of debris. These vibrations can cause the metal to weaken and expand on unseen fractures. Thus, you are reducing the firearms overall lifespan and compromising your firearm's integrity.
