Anyone try soaking stiff vinyl straps in some sort of conditioner?

Old bins often have perfectly strong straps but they have taken a tangled bent set & need to be limp again.

 

You could stick most of a strap down the neck of a spray bottle of conditioner & let it soak.

 

Anyone know a good trick to "unbuttoning" a strap that is thru the bino loops?

Without buggering up the plastic button?

I've used a small screwdriver to open up the long slot & manipulate the button thru it.

As far as I understand, vinyl conditioners like ArmorAll mostly just clean and provide a protective layer on the outer surface.  It will slow UV and oxidative damage, but it cannot reverse it.  Leather conditioners work by a different mechanism  and can help a dry and stiff leather become pliable again, but even then, everything does eventually wear out.

 

Personally, I'd look into finding a nice replacement strap, for comfort and safety's sake.  If the current strap's worth preserving for other reasons, it might be better preserved off the binocular anyway.

Problem with plastics is that they degrade irreversibly. That "new car smell" is the essential esters forever wafting away. I guess I could be wrong... but that's a rare occurrence.    Tom

Boil them

If they are of a thermoplastic formulation, that might be helpful.  Then dunk 'em in conditioner while still hot.
