Yes I do have a pressure washer. If I do it correctly as the instructions say to..I still have to scrub. It IS easier than before...less scrubbing, but I am still scrubbing.
Your cleanup efficiency should speed up a ton when you stop leaving the flooded image areas sit for 2 weeks.
Not to disagree, but I have been using the same $79 piece of crap pressure washer from Lowes for almost 4 years without issue. It is like $8 to get a full replacement warranty as well if it breaks. I know a few shops that have used the same machine and replaced them for "free" when they broke, but I haven't had to yet. It is 1500 psi and 1.3gpm. I leave it turned on all the time as well. I think I've only turned it off once or twice when moving my washout booth. I personally couldnt justify spending hundreds of dollars on one unless maybe i was using it 8 hours a day and had experienced a series of failures on my cheapo unit.
When you do gang use an old film to cover the unused image on the shirt side of the screen and tape around the film, just make sure the water proof side is away from the ink.
I think I see the main problem here. I need to get my screens as ink free as I can after I do a job. They will clean up much easier that way. Of course I need to learn how to do that efficiently. Also another issue...I have been ganging images on my screens and masking whats not being used at the moment. BUT what I notice is that after a job is done the ink is literally packed into the image that is not being used. Thats also the hard crap to wash out later.... How do I correctly mask an image off so that it can be used later and not get clogged up with ink? Or do I not gang images???
