Hi Max,
Enlarger lenses, because of the fact that they do not have to perform the numerous tasks that a camera lens does are generally a lot simpler in construction.
Depending on how the lens is put together, taking apart these lenses generally do not pose a major problem to take apart and clean by someone with the basic experience to do so. (I have taken apart a high-end Schneider lens before, and it was so easy because it was very beautifully designed and engineered - sturdiness and simplicity!).
Have a close look at your lens(es) and find out a little more if you can about their mechanical construction before you do anything. On the hands-on front, believe it or not, a mechanical watch repair-man can impart more practical skills and 'tricks-of-the-trade' as most mechanical watches and lenses share similar mechanisms - in principle at least.
For practise, go to one of the older camera shops or hunt around and get an ultra cheapo/non-functional lens to practise with if you like. That should pose a bigger challenge as these lenses generally have 'bound' up, dried up seals, parts and mechanisms.
After that, working on your own lenses should be easier.
Alternatively, get a friend who has access to X-Ray machines and ask him/her to ZAP your lenses on high settings repeatedly. Thsat would completely kill ALL spores, but it would not remove whatever has grown prior though.
