Nicely done. I assume the noise is also gone. I'm rather surprised
you didn't find any magnetized solenoids, because every one had the
problem to some degree. However, if you fix the pads so that there's
no metal-on-metal when the solenoid closes, the effect of the residual
magnetism is negligible.

Thank you.

Y'er welcome.
