Hello all- I'm doing some work on an older tractor loader that's been out in the weather with the hydraulic cylinders extended/ exposed, and they've developed some rusty "acne" - spots here and there rather than a coat of rust, but the spots (even though small) have raised/ rough texture. Obviously if they're run back "in" with the abrasive rust, it'll ruin the seals, and quickly. I realize that the "right" way to do this would be to get the rods re-plated or, apparently, replaced with new... but that isn't in the budget for this project right now. I'd appreciate any tips and techniques of how to properly, quickly, and effectively clean off the raised/ abrasive rust particles without further damaging the surrounding/ intact hard chrome. Thanks in advance for the help.
