Better to Throw Out Old C41 Blix Bottle?

[the.ronin]

I had not cleaned out a mix of Unicolor C41 chemistry in maybe 2 years. I rinsed out the developer and stabilizer Arista accordian storage bottles and they seem pretty clean. But the blix bottle had a decent layer of what looked like yellow micro crystals that formed all along the sides. As mentioned these are the accordion style so its particularly hard to rinse off the micro crystals.

Best to throw this bottle out and get a new one or is it ok to reuse it with all these micro crystals in it?
