Star San bottle melting?

I had bought a large bottle of star san several months ago. Now the pour spout is eroding away, so it is impossible to seal now. And when I pour it, leaks out of the spout area.

Is this normal? And what sort of vessel could i pour the rest into, so It doesnt go to waste?

Strange issue.

I would think that any plastic container with the same recycle code as the StarSan bottle would work. Or if you have a glass jar. Obviously properly mark the container.

Weird. Haven’t had that issue with any of my bottles. :?
I agree that a bottle with the same recycle code should work. Pretty sure its HDPE which is recycle code 2.
