PETG stringing like crazy on a Bambu A1 even after drying. What am I missing?

Filament was in a dryer at 65°C for 8 hours. Retraction is stock profile. Still getting cobwebs between towers. Temp tower looks best at 235. Help.

Found it. It was not the filament, it was the nozzle: a worn brass 0.4 that had opened up. Swapped to the hardened steel one and the strings are gone.

For anyone else landing here: wipe-on-retract and a slightly higher travel speed also help PETG a lot. And brass nozzles wear fast with anything abrasive, including some "silk" PLAs.
