Wash, not rinse. A good wash is needed not a "superficial" rinse.
I have never recommended a blix for film! A blix is a far cry from a bleach then fix! Consider that color film has about 300 - 500 mg / square foot of silver, but a color paper has 50 - 100 mg! All of the Silver metal must be changed into Silver salts during bleaching or blixing. This is generally not possible with films leaving one with a bleach bypass effect that cannot be seed easily by eye. So, please take care. You may be degrading your results.
