    According to Kodak " the agitation will form large volumes of persistent air bubbles." When I am done washing my film I manually agitate in Photo Flo (wearing rubber gloves to protect my skin). In the pass I had problems with scum buildup and tacky residue. I solved the problem by using Photographic Solutions "Multi-purpose Darkroom Cleaner" for cleaning my Jobo and Paterson reels. Helps to use a toothbrush.

    Interesting. Photo Flo is the one darkroom chemical it never occurred to me I'd want to wear gloves when touching. It's basically just detergent, isn't it?

    I develop 8x10 in a Jobo expert drum and fix with TF-4. I wash like this: 1 minute rinse, 1 minute rinse, 2 minute rinse, 4 minute rinse, 8 minute rinse. Each time using approx. the same amount of water as I used developer in the developing step. I figure it's a reasonable adaption of Ilford's washing technique to the Jobo, especially considering how quickly TF-4 washes out.

    Apparently, the wetting agent tends to coat the plastic if you let it dry out. I do not wash in my CPE2: I remove the tank from the machine and stick a hose in it and run water continuously for 15 mins. A final soak in distilled + wetting agent for 5 minutes or so.

    I wash out the tank and reels under a running hot water tap as soon as the film is hung up to dry; I don't give the wetting agent a chance to dry on the reels or tank.

    Cheers, Bob.

    Before the Jobo I used to just place the tanks under a faucet and let the water run inside the hole for ten or so minutes. Taking in account what Bob and Harry said, I have a question: will the use of a specialised hose like the one Jobo makes help the flow of water or is it just a gimmick equal to a normal hose?

    Arigram-

    Congrats with your new processor.
    Just curious where you found your new CPP-2? Did it come direct from Germany or elsewhere?

    Thank you Changeling.
    I ordered the processor from my local photo distributor in Crete, who ordered it from the Jobo representative in Athens, who probably got it from Germany. It came in pretty quickly actually and they had most of the drums available at their Athens store.

    On the topic of washing, should I use the same method and times for prints as well?
    Jobo states that the drums are not made for FB and I will be doing mostly RC anyway, leaving FB for trays.

    As far a film is concerned I usually wash by rotation on the Jobo and then finish off under a tube of running water into the middle of the tank. I have then used Ilford wetting agent by rotation and Yes it bubbles up like a bubble bath but provided you wash the tank and reels under hot water immediately afterwards I don't think you'll have any problems with the reels in terms of it leaving a residue on the plastic. Like Bob F I have never had any problems.

    Of course you can simply invert the tank a couple of times instead. In fact based on what we had to do on a college course which was simply to put the film strip into a communal wetting agent tank for about a minute and leave it, then it would appear that simply pouring the wetting agent into the tank and just letting the film sit there is equally good.

    I run 4 x 1 minute water rinses through the processor and then remove the film drum from the processor and do several water changes with running water in a Cascade film washer. 4 rinses in the machine are adequate for cleaning the machine. I move the film to another washer so it runs automatically and I don't have to tend to the machine further.

    If you are washing with reels, I think the holse they make is very nice. I especially like to take it on trips when I develop on location. I think it does a good job of regulating the proper amount of water flow thru the tank. Keep the water level in between the red lines and you are good to go. A few are usually popping up on eBay, so keep your eyes peeled.

    As for washing prints in a JOBO drum, if they are fiber prints I would be concerned about the back of the print receiving sufficient wash.

    That hose is not a gimmick or equal a normal hose because it is working like an venturi. That said, when the water runs it creates a vacuum in a hardplastic tube, this tube has a small hole and is wider than the hose, and take some air in the water. This is why the call it a quick rinse hose. I have such a hose as long as I am developping my own films and that is over 30 years now. Rinsing al my negs. not more than 5 minutes and no hypo or somethings like that and all my negs. from 30 years ago are still oke. It safes also a lot of water.
