Dehazer the green stuff not working
I'm new to screen printing and need some help.
I've just got my pressure hose and green stuff from the mail
brushed it on both sides. Left Green stuff on the screen for 10 min, pressure hosed it on the print side first then the other side.
Still has faint ghost image on there.
What am I doing wrong?
I'm afraid to leave it on longer because if heard of it locking into the screen
Thanks in advance

Like Dave said, it sounds like you're using something like Simple Green, which is just a detergent, not a de-hazer.
As for de-hazers, I've never heard of them locking in emulsion. I think you're confusing them with emulsion removers, which will if left on to dry. I've slopped Franmar's De-Haze Gel and Chemical Consultant Renu-It and left them on for hours with no ill effect. There are some caustic de-hazers that will eat the mesh itself (or weaken it) if left on too long.

I have this same problem.
I had a screen with really bad ghosting and dehazed it but the ghost image was still there and barely removed at all. I thought maybe I didn't clean all the knuckles of emulsion completely so I went back to the scrub and emulsion remover along with our 1500 psi pressure washer again. I dehazed twice after that and we can still see the image.
I bought a package deal when it was very cold and think it may have froze in transit, that or just a bad batch. I am starting to feel like the bad luck guy because every step of the process for us has had problems.

The green stuff is a dehazer. If your ghost image is clear there is no need to dehaze and will not remove the clear image. The clear area of the image is due to the squeegee altering the mesh and possible slight bleaching from the UV exposure. Over time they will reduce with further use of the screen.
Dehazing is only to remove ink stains in you ghost image area.
The green stuff needs to be shaken well as it contains a abrader and if you don't you will be left with half a bottle of abrader. Also using this as your only dehazer is a bad idea as the abrader will break down the mesh. I will use it 1-2 times on a new screen and the use something like liquid renew dehazer as its uses caustic salts instead of some of the other toxic chemicals most use. Most dehazer use a paint stripper that is very toxic and should be used with caution.

Thanks very much for the info. I did call ryonet also and they said that it was normal to have a faint image from the last print on there. My lack of experience thought it was suppose to wash out completely. I am working from home and I have dogs around so I will have to be extra carefully about using this stuff.The green stuff is a dehazer.

that specific dehazer is 'environmental' friendly so it's not the caustic type of dehazer that if left on for too long will eat through your mesh and you also don't have the worry of washing it down your residential plumbing.Thanks very much for the info.

but do keep your dogs away from everything when it comes to printing at home.
