good stuff for cleaning
You can use one of the citrus cleaners available at any grocery store to clean your winch. Much less messy (and caustic) than a typical solvent. It's actually quite easy and should be done at least every couple years. There really aren't many parts. If the boat is in the water, also hang a cloth, rag, etc. vertically around your work area to avoid losing any parts (some are very small) overboard. Good luck!!!
