I wouldn't bother with that oil stuff. It sounds like a way to suck more money out of your wallet. A good soap and water bath work good for a general clean, and then I disinfect with chlorhexadine spary. It's awesome stuff! No worries with chlorine fumes and pretty cheap. Here's a link to it.

92-94 is a good range for your hot side, and 82-84 is good for the cool side. You can use plexiglass or plastic wrap to cover up part of the screen to keep in humidity. And don't worry about the all in one piece sheds. If it all comes off then your doing great, and if it doesn't then just do the soaks. It's important to get the eyecaps off and make sure that there is no shed encircling the body. This is a great community and very friendly and helpful. If you have any questions don't hesitate to ask.
