What are any of the ointments or lubricants you can use to probe your snake? I ask this since I hear so many mixed responses as it what is good to use and not good. For example, some people use Vaseline and others think it's problematic because of the oils. I also hear some people use regular Neosporin, and that KY jelly is one of the best to use.

So post any and all ointments or lubricants that are good and not good!
