Around mid-2016 we had a batch of this product that had some glue which did not rinse away as quickly as it should.  If you have this issue, we have found a solution:  Pour Dawn dish detergent on your project, and smooth it over the entire affected area (with your fingers or a foam brush); allowing it to soak for a couple of hours this way.   Then wash the project with a regular load of clothes or hand-wash and rinse thoroughly (hot water is best).  We apologize for this issue but feel it is most important to provide you with a solution for your project.  Feel free to contact patti.lee@sulky.com with any questions.
