Anyone have experience using recycled Ilford Multigrade bottles to store CineStill Cs6 "Creative Slide" DynamicChrome Kit (E-6) Chemicals

A friend is going to try some E6 at home processing and I am supplying the bottles...

The Ilford Multigrade bottles have been thoroughly cleaned with hot soapy water and multiple hot water rinses.
Any reason the bottles can' t be used to store the kits 3 chemicals.
D9 “DynamicChrome” 1st Developer (i understand this is a one shot liquid concentrate, bottles would be for storing working solutions for imminent use)
Cr6 “Color&Reversal” Color Developer & Reversal Bath
Bf6 “Bleaches&Fixer” Pre-Bleach & Blix Bath

Thanks in advance

I've been re-using Ilford developer bottles for decades, including for E6 & C41 chemistry. While they don't last forever, they do last a very long time.

I don't expect you'll have any problems with the bottles. Unfortunately though the CineStill E-6 kits have had mixed reviews compared to more standard E-6 kits.
