Bleach? On skin? Even diluted? I don't think so. That borders on barbaric. I would really be interested in hearing more about this treatment(?). It is definitely not something I would use here in our rescue. I would think that bleach would not only irritate but would also dry out chapped skin....which is already too dry since it's chapped (not to mention the toxic effects of transdermal ingestion of the bleach).
I do agree 100% with Pam in using the Udder Cream....and we have also used Bag Balm as well as SSD. My concern would be why we have this condition to begin with. It could be that he is using a crock. Could be from syringe feeding....we see a lot of "milk scald" in incoming wildlifewhere untrained people have attempted to syringe feed. But considering your past posts regarding the weepy eye and now this, I think it would be prudent to at least entertain the possibility of a dental issue. The use of Baytril concerns me for several reasons....including the fact that it's not very effective any longer. One, if there is an infection, it needs to be identified....not have antibiotics blindly thrown at it. Many times when you have a rabbit displaying weepy eyes, wetness around the mouth (commonly called "the slobbers") and signs of infection....I would so some serious investigation into the root cause of the problem. Dental issues can afflict any breed of rabbit but are very common in the flat faced rabbits like Holland and NDs. One of the prime indicators of a bacterial infection is a slightly elevated body temp....did the vet get that? URI and/or dental issues can present themselves as eye issues.
I hope I am way off base on this one....but all the presentations you have mentioned do bring up the possibility of a dental issue. I hope it will be considered and investigated. If this rabbit were in our rescue, my initial probe would be to do a full diag on the teeth.
