DJ; I don't know if the techs have changed their minds on "Sewers Aid". When it first came out, we were all using it and loving it! We were using it on spools of thread and our needles. We were soon warned that it was 'gooping' up our machines! I LOVED the stuff, it made difficult threads more manageable. Sooo... just wanted to send this along to you. Obviously up to you as to what you do. Just my 2 cents worth.
