Battery Compartment

My battery compartment is unbroken but still has lots of what appears to be residue from the battery.

I have scrubbed and treated the area with baking soda and it is a lot better. What is the ideal method for removing the remainder of the residue? The residue is whitish in color.

It better get warm soon or the body may be off soon!

try scrubbing it with a toothbrush with denatured alcohol or again with baking soda, rinsing it well with water.

Thanks! I will try it and let u know.
