anyone have any tips on how to clean a swingarm hydrometer??? thanks, Greg

fill it with diluted vinegar and let it sit for a few hours then rinse with water

Rinsing after use with fresh water helps.

Want accuracy go with a refractometer, I've never regreted getting one. you don't need an expesive one to get good results.
I agree with the others I have used vinegar and RO water in my old hydrometer.

got my refracto for 40 bucks shipped and keep my swing arm and glass lab in the closet

Just for fun measure your salinity with both, let us know if there is a difference.
