I drained the moisture out of the tank of my air compressor a couple days
ago, and when I did it, this yellowish greasy substance was "mixed" with the
moisture/water that came out of the tank.
At first, I thought it was the compressor oil, but I check that and the
level was fine....plus, compressor oil isn't yellow. And this yellowish
substance isn't rusty colored...it's yellow.... I'm baffled. It's a 5PH 25
gallon Campbell Hausfield compressor. And, I've drained the moisture before
and never experienced this.
Anyone have any idea what this could be?
