From the Aleene's website there are 3 Tacky Sprays but only 1 for fabric and it is permanent. So definitely not the same as basting spray. I like 505 best - found a bargain on Dritz basting spray but I did not like quilting through it.
Hope you can get the gunk off SBG!

Definitely not a basting spray. All basting sprays will have baste or temp adhesive on the label and all wash out so water will remove basting spray if on your machine. I have tried the new basting powder and it's great. No spray!

...... plus it is advertised as an adhesive,
which to me, sounds much stronger adherence and a different chemical composition
than a temporary basting spray.

It's nice to seek out alternative products,
but sometimes it is best to stay with those created for the intended use.

I couldn't find the Un-Du at Walmart so I bought something else that looked as good. It's called Goof Off. It worked like magic! I just drizzled it on the sticky parts and then stuffed a little cotton swatch in to clean. All the junk came off. It seemed to dissolve the sticky stuff on contact, first try. Great stuff!

So, I can quilt again! Thanks for your help with my problem, everyone who responded. :)

I'll have to look for the Goo Off, haven't seen that before. I don't like Goo Gone, it stinks.

Goof Off does a very good job on sticky stuff like tar, chewing gum, etc.
But be warned, it stinks. LOL

Yes! Goof Off has a very strong fume and is very flammable. You should try not to breathe it. But it worked wonders. I don't like Goo Gone because you have to scrub and scrub, and then do it again. It's not strong enough.

UnDo is the best for anything stuck with adhesives. I asked a photo restorer to order me a big container of it.

WD40 spray and wipe.
