Title: Warm water when rinsing screens... 4/10
Post by: DCSP John on April 10, 2014, 09:20:36 AM

Hey Everyone...

We've never used warm when rinsing out images. Always cold.
Pierre mentioned something a while back regarding warm water in
the production area... Does using warm water make rinsing images out much easier?
My guess is yes, but would like to know how many of you use warm water in this step.

Thanks.  John

I feel it does but , the warm water can mess with some pressure washers & break down their internal components much quicker.

we have an aquarium heater in our post-exposure water tank... helps a LOT in rinsing out.  the open areas are nearly falling out as we pull the screens from the tank a minute or so after we put them in.  No problem at all with the exposed areas.

We then use cold water with the pressure washer to rinse the screen.

I use slightly warm water for development, but do not use a pressure washer.

Don't know about to develop a screen, but warm water helps in the reclaim

When our hot water heater crapped out several years ago we never bothered reinstalling one. I have not really noticed any difference in reclaiming or developing tho I am sure reclaiming would be a bit faster but not necessary.

I'd kill for a hot water pressure washer as the final stage of screen cleaning.

we use hot water just to develop/rinse. The pressure washer is using cold water.

I used a diesel or kerosene fired one at Andy's that we got new at Cresco. Maybe they sell retired rental ones at a good price

Reclaiming was not as easy back then, what with xylene actually hardening emulsion and all, and no dip tanks, so yeah, very hot water helped!
When I first got there, they were running one from the water heater drain.
Then, I got the Mi-T-M from Cresco, and it kicked ass!

Yeah I'd imagine hot water would be awesome.

Not sure about running a diesel or kerosene heater inside though...

Yep, I was outdoors, rain or shine, though I was mostly under a roof.

At a automotive shop I worked at in the late 80's I ran a diesel hot water pressure inside.  I permanently mounted it and welded a pipe out the wall for the exhaust. I am thinking of doing the same thing when I put the addition on my shop.   

I am going to try warm water for developing. I seen the mention of a aquarium heater but those are expensive in larger sizes.  A livestock deicer will keep water around 90-100 degrees. Does anyone have a recommendation of what temp to keep a developing tank.
