How do I clean system data on LG Phoenix 2.

I have been using my LG Phoenix 2(k371) for a few months now, but have ran into an issue.The phone says it holds 16gb, but on inspection I found 6 of those are system data.I've used Android for years and this does not seem right. I know that on Samsung phones there is a code I can dial to clean this up, but I don't know of such code for this phone. How do I clean this memory up?
