Four weeks ago I removed a 2100 booster from Chem Dip to clean it up. The more I worked on it the worse it looked. It had shallow pits that roughened most of the surface. Figured it was something not noticed before it went into the dip, and that some nitwit had blasted the hell out of it with coarse grit media. Another possibility that came to mind was that the carburetor had previously been soaked in acid.
Today I removed a 2100 booster from Chem Dip. Same deal! Gave it a lot of thought and believe the boosters were in for too long and succumbed to galvanic corrosion. They seem to be acting like a sacrificial zinc anode.
The container is aluminum. Other parts included aluminum steel and brass along with the boosters, which were in for 5 days. Longer than usual due to some things that have come up. No harm was done to any of the other parts. Another strange and hard learned lesson. Both boosters are beyond use.
