Sorry I don't think making a deadly stuck lens fully funсtional in about 5 to 10 minutes is 'making things worse' . Done it to dozens of lenses, and always with 100% positive results. You don't use those - that's perfectly OK. But have you ever tried them - I mean exactly the same hose clamps as shown above (I actually don't know what is an oil filter wrench) - before stating they make things worse?
On the other hand, I have left one lens with penetrating oil on the threads for a couple of years with absolutely no results.... And I think it's the crawling oil inside a lens barrel that is the thing that makes optics worse. I don't use any oils any more.
