Sigma Lenses With Fungus

lvl. 1 (Lens-Learner)
I have 3 Sigma Lenses with fungi growing on the interior of the lens elements.
Sigma AF 70-210 f2.8 APO
Sigma AF 28-70 f2.8
Sigma AF105 f2.8 Macro EX
The two zooms were purchased back in the '80s when I bought my Nikon N8008.
The Macro was bought several years later.
I have finally made my move into the digital age.
I bought a Nikon D610 and immediately noticed the image degradation caused by the fungi.
I have begun to replace these lenses with updated versions beginning with a Sigma 70-200 f2.8 APO EX DG OS.
I'm very happy with it so far.
So, instead of outright scrapping the old lenses out, I want to try cleaning them myself.
I am looking for advice on how to go about disassembling these lenses, or advice on where to get that advice.
As I look at them it appears that I'll need to begin at the back [bayonet] end and work mky way forward needing to almost completely disasseble the complete lens to access the front element. I hope that I'm wrong. But if not, so be it.
