How would one go about cleaning up shiny latex from smudges?

the first important fact is to recognize what you are looking at. that's not "smudges". it's latex that hasn't been cleaned nor had proper care taken. it has overall dull, patchy areas and a bit of shine. the hood is better, it just has fine stripes that can be removed with high pass work. they need to be properly cleaned and then a silicone lubricant or other latex polish applied (for shinny latex) just before a shoot.

you need to do lots of work taking out the dull areas and adding shine in. this wasn't featuring the latex suit, but eowyn still applied silicone on it before the shot.

You can fix anything because control everything. It's a question of how mush work you are willing to do.

I'd consider painting the latex a solid colour and then putting a light map over the top to get basic contouring back in, then another for specular effects.
