Miro. I've come across 456 post '95 that was good. Seems stuff made in Alabama is the newer fixed formulation. Anything Redwood City has gone bad. (From my experience )
I'm not really sure what year they found the issue...and what year that started using the better formulation...or at what facility. I think that's why there's several years of gray area where you just have to check it to know for sure.
I also think that under certain conditions, even with a good formulation, tape can get mild sticky, but it's not that same SSS thing, where it's literally falling apart...and sometimes a few passes, and it cleans up and settles in.
I've use a lint-free wipe, wrapped around a pencil, press against the tape gently, in RW/FW to clean up the tape....but you gotta be real careful...one wrong move, and you've got pencil and tape flying.

With the 2" tape it takes a firm and precise hold...you have to press just right. With the narrower tapes, there isn't as much tape to pull on the pencil wrap.
Anyway...2-3 passes, and the exess crud comes off, and then the tape is fine...but for true SSS, it doesn't work...only baking, and it's only temporary.
I've baked tapes that had the non-SSS mild crud/stick...and it's more about drying them out than it is about "resetting" the chemical formulation. You don't need to bake them as long as you do with SSS tapes.
Did you ever pick up that food dehydrator?
I think I gave you an eBay like to the kind I use awhile back...it was a good price.
