How would someone clean vintage acetate taffeta?

I bought this vintage late 50s acetate crazy iridescent taffeta party dress on Ebay last week, there's no current stains on it.
But-- if I wear this out and something happens (sweat, food, etc.) gets on it and I need to wash it, what would be the best approach to cleaning acetate taffeta? I saw older posts on here about a 50s acetate dress having 'the suds being worked through it, rinse in water, do not soak' but I am not sure if that dress was taffeta, it didn't look like it or say anywhere in the post that it was.
If I spot clean this thing I am not sure if acetate taffeta will water stain, or if the acetate will lose its scroop or rustling effect. Does anyone have any advice? I feel that the chemicals in a dry cleaner would just be too harsh on something like this. There's also a (what I think is nylon) netting inside of this. Would that netting soften too?

 

I would dry clean it, definitely! Washing acetate taffeta will permanently change its texture, if not ruin it completely. Acetate taffeta is fairly sturdy in my experience--much more likely to survive a modern dry cleaner than silk taffeta would be.
