Both good objections! I suppose if the peroxide is produced during storms, and has been doing so for a long time it could have reached quite high concentrations in some regions, mixed in with soil and ice. As to the question of how it behaves at 6mbar thats up in the air (pardon my bad pun), I can't find anything on it. Theres no reason to supppose hydrogen peroxide over any other possible candidate, other than the argument for its production on mars has already been put foward in detail. Personally I'd favour H2O2, or something like, as 'antifreeze' for the gully water over salts ,which are frequently suggested, because it lowers the freezing point by an extra 30 degC, which would make high latitude polar gullies easier for me to accept as water related. I've not done any legwork on the idea, it just caught my imagination. I'll do some more digging and see if I can come up with some numbers.
