How big is the tub you’re soaking him in…if you are using a 10% solution of iodine (commonly found at drug store). Just a few drops, just enough to turn the water a light tea color, not coffee. @ostap sorry for the late responds brother I’m at work. 5 to 15 minutes…room temp water remember we hover above 90 degrees in body temp, so if it feels warm to the touch, them its probably to hot for the snake.
And just go once a day for now
