For my Pro-Line which is pretty much the HDPE version of an AP PVC cage, I spray it down with Chlorhexadine, let it soak for about 10 mins or so, then wipe it out and let it dry another 10 mins. Then I throw in new aspen and put my BCIs hide and water bowl back in. I do the same for my BP cage. A little Chlorhexadine residue wont hurt reptiles so I don't worry too much. I spray her water bowl and hide down with Chlorhexadine too and then rinse those off. Your method is fine. If you use F-10 SCXS, from what I read, you need to wipe that down with a clean wet rag after as its a cleaner AND disinfectant. I probably would skip the vinegar if you are using F-10 SCXS and just use that and then wipe down the cage with clean wet paper towels.
