I've done both the bake & the soak. I found if they are green branches- recently cut- they sometimes get sticky and almost to smooth for his sharp little nails to grip on to well when wet from misting. However, if they are already a bit dried out this is my preferred method. When I used the bleach water to soak they seemed to kind of hold on the the moisture and even after tons of fresh clean water I still felt like it was questionable. I do like to clean them with a little bleach/water when I clean his cage. Only wipe & rinse, no soak. I also have had problems with the bleached soaked branches getting small mildew spots on the ends. Not sure why that is but not a problem with baked. Its all a lot of work though & if other more experienced keepers have not done either & not had any problems, I'd follow their lead.
