Replaced my now tattered Kapton tape with a new sheet and adhesion was iffy at best. Acetone, IPA, and glue stick didn't help matters. Finally scrubbed the Kapton with Bon Ami, rinsed well followed by an IPA wipe, and all is well again printing on naked Kapton.
For those not familiar with it, Bon Ami is a grit sold as a sink cleaner in the USA. Not so popular any more, as it badly scratches anything you use it on, being mostly ground limestone (calcium carbonate) and ground feldspar. I'm guessing the gazillions of tiny scratches made the difference.
("IPA wipe" being a flood and drain with an isopropyl alcohol soaked cotton ball, not an evening with a six-pack.)
