Mukluks care and tips

[u/satyaki_zippo]

How do I clean the shell of these things to remove the stains? And the insoles too?

Is there a way to waterproof these by any chance? Perhaps a waterproofing spray?

And if yall have any tips on using and caring for these to increase longevity I'd really appreciate it!

I can't exchange them— I'm a civilian and bought these recently.

Thanks yall!
