Sherwood dry bleed - contaminated piston

[fmerkel]

I started a thread in the [Regulator] section because it involves non-shop work on regulators. If any Sherwood regulars or one of the reps want to participate it's located here. In a nutshell the dry bleed system is no longer working due to contamination of the piston port/plug. Once contaminated it appears impossible to clean. I've tried a lot of methods and chemicals. It doesn't work so I feel like I have nothing to lose.
