About 10 years ago I left a Mojo/Split Shot Kit in my cousins boat and the slip sinkers and Split Shots became oxidized or covered in a calcium like powder. What's the easiest way to clean up this old unpainted lead ?

Soak them in baking soda and warm water over night and rinse and dry. If any residue is still on them soak in 50-50 white vinegar and water,  rinse  and dry.

I use straight white vinegar over night, then rinse with clean water and dry.

And then cover them with an oil based bass scent and it will not happen again.

Ya'll sound like the kind of guys who would scrape the patina off Lady Liberty. Why are we doing this?

For the time and effort compared to the cost of new lead, why not just buy new?

Thank you for everyone's input....it's about $40 dollars worth of Mojo Weights and they are the color of chalk....if I can remove the oxidation then it's a success and a savings. Plus I'm very particular about how my tackle looks and works.

Man....For pennies you will be able to use those sinkers again without worrying about it.

That powder/corrosion is lead oxide, which is toxic and more easily absorbed than lead in its metal state.

Don't breathe it in when moving it around.

You don't want to brush the oxides off the lead they become airbourne and toxic. 

The white oxides are a corrosion bye product from impurities within the lead caused by poor air circulation. 

After cleaning and rinsing wash your hands. You can spray the clean lead with WD-40 to help seal the lead and store sinkers in containers with holes to help air circulation. Air tight boxes are the problem storing lead sinkers.

Or switch to tungsten.
