Sealer or wax or polish…?

Submitted to Product Chat

Hello to the experts. Happy New Year!

Wood care question for teak please.

I was fortunate to find and purchase a set of vintage 1960s Michael Lax for Copco Danish cast iron enamel cookware many years ago. 

Currently the teak handles in the handled pots look and feel dry.
I have never treated them over my many years of ownership.
Maybe this is something that should have been addressing regularly and I have been negligent.

Would the experts have a suggestion to remedy….a possible treatment to seal or nourish the teak handles? 
Was hoping for a wipe on product if one might be available.
Unless a plain wax wood polish or Whink Kruckenbergs might be considered?
