Don't Throw Out Your Solar Lights Just Yet.

I thought my solar light batteries needed replaced until I saw the battery compartments were corroded. So I took to the internet and found 2 options, white vinegar or baking soda and water mixture, neither worked. Then I remembered the old remedy I had used to remove tarnish from brass, ketchup. I didn't want to throw them away because they were still in great shape and I didn't want to have to buy more, so what did I have to lose but a little ketchup.
This is what they looked like .
I slathered the ketchup on the contacts and the springs with a Qtip. Then let them sit for quite a bit of time.
I cleaned them with a Qtip and water. Some were more corroded than others so I reapplied more ketchup. Cleaned them again and let them all dry.
This is the end result, no more corrosion.
After letting them dry, I placed a ( regular ) battery in the compartments to test them. They now work !

    Is it the vinegar in the ketchup and the thickness of it makes it stick to the contacts?

    I'm going to try this as I have a lot of solar that stops working because of rust!

    This is a good idea...gotta upcycle...think most of us just get tired when stuff like this stops working...but it was $¢ spent, anything decorative is landfill stuff and should be prevented. I will attempt the 'cleaning.'. Throwing out stuff is going out of style, fixing is in.
