Not so fast Box

Our underwater camera leaked and Gringo saved it.
He says: Open all possible covers, lids, etc and remove batteries and memory card. Open it as much as possible. Then Gringo put it in the oven on the lowest temperature possible (170 I think). He baked it for an hour or slightly more with the oven door cracked open. Closed all the hatches while it was still hot. Put it in a ziploc with some silica gel packets, remove as much air as possible and seal. Let it cool sealed inside the ziploc (better use freezer bags!). Once it's cooled off, you'll have to open the hatches on the camera through the ziploc so that the first puff of air that goes in there is nice and dry.
And he's still using it!! We don't take it underwater anymore but have taken hundreds of photos since then.
He also says that if you don't want to bake it - put it in a ziploc with the silica gel with it opened up and hope for the best.
