It's fine to leave the film on the reel, in fact it's safer.

However in this case the OP needs to used de-ionised or distilled water for the final rinses, it's a glaring hard water issue.

BTW Rick alcohol is great for drying film but if you bathe in 3-4 baths each with higher alcohol content the last 98%+ the film dries two minutes later Getting that grade alcohol is the issue though
