I've done strip clearing tests some two weeks ago. By then it was fine.
I've used Tmax 100 before with it, and no problem.
As I said, it was age and not exaustion. I've counted all the strips I've fixed and it's hardly equivalent to 4 36 rolls...
Funny, it never happened to me in the past - but I've never used Polymax fixer before (the only ready mixed stuff one finds over here). Is wearing out a characteristic of rapid fixers ?
Well, one more soup recipe to mix at home...
