I've found it best to not wash right after use, but to allow about two weeks of airing out first. Even then you might have some gluey lint stuff if you sprayed heavily. particularly check during drying (like for baby quilts) and remove while damp if you can. I always sprayed too heavily at first -- for years even. I had access to a long arm for several years and didn't use spray baste. A couple of years ago I started doing them at home again, and the first one (even knowing what I know) I sprayed so heavily I waited two weeks just to quilt it -- good thing I wasn't on a deadline. It might just be my vision issues, but if I can see where I've been, I've sprayed too heavily. If it feels damp or discolors the fabric, that's waaay too much.
While I don't usually use drying sheets, this might be a time I'd consider one if you are on a deadline and about to present a quilt to someone.
