I wrote to the Odif company about there 505 spray and the can directions to remove adhesive by dry cleaning. Here is there answer:
Dear Sue
505 is the leading basting / Embroidery spray in the market and has over 50 years history on fabric and it is the only spray in the market that was developed especially for use with fabric and thread. Over time 505 will dry and break down during washing and if possible will migrate out of the fibers during the wash. However, if you never wash the quilts it will do no harm. The propellant evaporates and only thing that holds to your quilt is the adhesive and it is an inert resin that does no harm or change over time. You will never know it is there.
I hope 505 saved you from traditional basting and helped you make a wonderful quilt. Please contact me if you have any additional questions.
Best regards,

Now I'm still not sure if I will continue to use it! It does make basting so quick and easy.
