Tbh, I wouldn't be very hopeful that bobbin cleaning will have much if any effect.
But still worth a try.
I have found that just sticking a screwdriver through the hole in the bobbin as a lever and wiggling it around while spraying with brake cleaner is quick and effective.
No need to spin the bobbins in my experience.
A warp that is visible to the naked eye must be on the large side ..!!!!!
