Vapor polishing TPU/Flexible Filament

Greetings all... I've been reading about vapor polishing ABS and PLA printed parts, but after spending almost an hour searching and rephrasing it every
way I can come up with, I've not come across anything on vapor polishing TPU printed parts. I know the stuff is fairly new, but surely someone has done it.
Is acetone an option, MEK, DMF, or ?? Maybe it just doesn't react like ABS and PLA do to vapor...
Inquiring minds want to know...

Any thoughts folks?

Thanks!

Ron

Polyurthane is chemically inert, I don't any option for vapour polishing.
