So I was cleaning an especially dirty balance spring with B-dip because several turns were sticking together. However, after a wash and dry, it seems there are more turns sticking due to the B-Dip. I can see it clearly in-between the spring turns and it is not evaporating. I even stretched the spring upwards a bit to let them air out and they continue to stick. This is after two washes. You can still see the liquid between the springs. Not sure if anyone has seen this, but I don't know if this is an indicator of my dip going bad or being contaminated. I would rise with IPA, but the stud and collet aren't pinned--they are either glued or shellacked so I won't risk it. If I keep seeing this, I'll probably switch back to a heptane or naphtha for this type of cleaning, but I wanted to see if anyone else has seen this with B-Dip. -

I only watched the start, but he's out on magnification by a factor of 10. It's 7X to 45X, not 450X -
It's one of those tools like screwdrivers and tweezers, where it's worth spending more for the quality. And it gets used all the time. At about £20, the 4040 is not expensive for Bergeon. When putting a watch in dial down, you have to be careful not to catch a sweep second hand, but once secured, life is easy - two hands available to work on the stem.
