I mix my TF-5 in 1000ml working solutions all the time. I pour the remain stock into 250ml bottles since that is what it takes to make 1 liter and don't have to worry about air in the bottle. One liter of working solution is good for 15-18 rolls of film.
On a clipboard hanging on the wall I mark the date and the number of rolls processed. I prepare a new working solution at 15 rolls to be safe. It only takes a few minutes to prepare a new working solution and you're ready to go. So a liter of stock T-4/5 is good for 90 rolls of film for me.

That should do it.
A hands-free method of washing I employ is I stick a hose down through the center of the reel (assuming stainless reel) with the end cut at 45 deg angle and about a 3/4 of inch past. Place the assembly back into the tank and the hose is attached to a funnel clamped to the faucet. I turn the water on slowly and it comes up from the bottom of the tank and out the top for a slow, continuous exchange of water.
I also have a modified hose you can get from the darkroom supply store for that. It has a rubber end that you can stick on a faucet but that doesn't work on my current faucet with a flared end.

Are you fixing and washing long enough? I've never had a roll come out with any.

I also use TF-5 fixer (or TF-4) because it is a requirement (non hardening ) for PMK Pyro. Fixes "regular film" in 4 minutes and T-max films with its magenta stain in 6 min. And it doesn't need an acid stop bath or hypo cleaning agent.
