I am having a problem with the dye continuing to develop after I have set it on 100% cotton fabric. I have been using a capful of the special detergent in boiling water and then leave it for an hour, moving it every now and then. The print looks perfect at first but when I then leave it in the sun to test, the white areas start turning green! This is obviously not ideal when planning to sell a product, so any advice is much appreciated thankyou!!

It actually sounds like you are getting all the solar fast out of the print. The problem is that it is in the water at a high enough concentration that it is getting dispersed through the whole garment.

You need to change the water at least once. What I do is rinse the print under the hot tap before I soak. Rinsing out as much of the dye before I do my soak. Then I soak, change the water once, and soak some more.

Even doing an additional rinse with the solar fast wash after you boil to get that last bit out will help.
