Lens cleaning - Help!

I recently purchased a box of lenses almost for free (very cheap). Well, alot has fungus on them and I want to clean it myself since I think the cost of cleaning of some these lenses exceeds their market value.

Do you know a website with step by step instructions on how to open, clean and reassemble a lens? What equipments and solutions do I need etc... I have autofocus and manual lenses.

Hope you guys can help me.

Thanks.

Do not use any alcohol containing product as some fungus react in the opposite manner you are going for - it might actually get worse

I can't help you with the disassembly but apparently Ponds Cold Cream is an excellent fungicide that is as gentle on your lenses as it is on your hands.
For myself, I won't keep a fungus infested lens.

Here's a link for stripping down a 50/1.4

Pentax 50mm f/1.4 strip-down instructions

Most lens come apart in a similar fashion, besides the tools it helps
to have a real good memory and maybe take some shots of the lens
as you proceed. I've done some primes and a zoom, zoom being the most difficult.
Do a search for disassemble (name of lens here) theres info out there
but it's limited.
