Cleaning darkroom tubes : LUSENET : Large format photography : One Thread

The insides of the drain tubes leading from my print washer seem to have grown some mold. They are turning black. The ones leading out of the Jobo are a lovely pink like that mold that gets on the snow fields in the Spring. I wonder if anybody can tell me a way to clean these. Thanks

Rinse them out with a fairly strong Clorox or other household bleach solution. Let the bleach sit for a few minutes, then flush with clean water. Should take care of the problem.

How about Jobo's processor cleaning product?

Jobo warns against using bleach. I'd expect it to be ok for plain plastic tube though.

Tom, The bleach will work fine but I would rinse it with good ol vinegar after which neuteralizes it and removes any bleach residue that remains.

If you do use vinigar (or any acidic fluid) to neutralise the bleach rinse the bleached items well with water before you use the acid. Best wishes. Pete.
