Clearsoft is another name for Ironall for lights.
I used to use Ironall, but it has fade issues. If you search "ironall fade" you will find many threads from users reporting fade problems. I was one of them. I did find one shirt (tested over 12 of them, different brands, mixes of 100% cottons and 50/50 blends), and I found one that was colorfast with Ironall, that was the Jerzees HW 50/50 (29B).
Jetprosofstretch is colorfast with any of the shirt brands I've tried it with. The biggest difference now is not "does it fade?", but how noticable is the window, and does the tee shirt pill or suffer fibrilllation (tiny fibers that lift and give the shirt a prematurely faded appearance when it is not. Ironing down the shirt usually brings the vibrancy back, when you can do that, it's fibrillation and not fade.)
With JPSS, I am no longer limited to using one shirt like I was with Ironall. I enjoy the freedom, knowing I can be confident that the shirt does not fade when I use JPSS.
Not everyone gets fading with Ironall, I know I did found a way to use it successfully (with the Jerzees) - but more folks do get fading than don't. Also, with Ironall, the fade isn't *immediate* with every brand of tee shirt (although it sometimes fades on the first wash
). So anyone who tried JPSS might be happy to see their shirts can go on and on past many washes without fading.
Here are some pics of shirts done with JPSS, one shirt is pigment ink, the other Canon regular dye ink. The shirts are being bleached in the test.
I always recommend getting sample packs, and testing with your own product combination to see what happens and what gives the results you are looking for. If you test products, it's easier to see *why* you use them. Some folks just go right for the JPSS and never look back.
Good luck to you all, no matter what anyone decides to use, and I hope this info gives some food for thought, and a variety of information to base choices on. Money will be spent, so make sure it's what you think you really want to spend on. I'm sitting on a stock of Ironall light I won't use for tee shirts.
Just trying to help someone avoid the same thing.
