So, that insight we bought last September so far seems mechanically sound, but, so, so dirty. I'm not sure how best to approach it but waiting till spring because our garage is not heated and it's cold as shit up here in MT.

My biggest concern is safely removing all the little mouse poops that are literally everywhere except in the cabin. I fashioned a cardboard cone with gorilla tape to our shitty shop vac to clean out the spare tire well but I'll probably need a smaller cylinder to reach them in the engine bay and battery compartment. On top of that it seems like dirt/dust is underneath all the trim. I believe the previous owner lived off a gravel/dirt road. It's the kind of dirt that doesn't wipe away the first time, and I don't want to ruin the dash/plastic/vinyl miscellany with harsh chemicals.

Insight is mostly aluminum so I need to double check cleaning methods to avoid. I've taken dish soap+bronze/plastic brushes to the back of the wheels (also aluminum)but sandpaper has been better. Haven't touched the front of the wheels with the sandpaper as it seems to have a gloss coat of some sort on it and would prefer to have its replacement on hand before removing it.

Ideas?
