interesting...I have never heard of this. one of the items is a calculator that doesn't really have any solids in it, but just a bunch of oily shite that came out of the batteries. can I flush out the calculator with this product?

It’s worth a shot, but no guarantee. It’s contact cleaner, so the stuff is specifically made to remove corrosion byproducts (e.g. rust or copper oxides) from electrical connections. Not sure what the oily shite you’re referring to would be.. but I’d try if I were in your shoes.

I use the D5 formulation, which is in a can with a straw nozzle like WD-40. According to the label it’s safe on plastics. I would still probably try the D100 (solvent-free, whatever that means) if you actually have to apply it ON a circuit board but I’d try the D5 first in the case of a battery compartment.

With anything like this, always test it on a non-critical piece of plastic before going ape shite just to be safe.
