Iso-propanol (also known as propan-2-ol, or 2-propanol) is generally considered to be highly suitable. You'll want a high purity grade to prevent muck being left on the lens afterwards).

Thank you so much for your prompt reply, I will look up for it, am pretty sure AmaZZon might have it

It sounds like you need to invest in a system for keeping the humidity down in the area you store your lenses. Fungus only grows when the humidity is high enough. A drying cabinet might be the ultimate solution, but a bag with silica gel pouches can be sufficient IF you dry them frequently.

The lens was probably store in a dump environment, it was a present I got in the late 90s if I recall correct, none of the other lenses I own, fortunately, developed any.

Grazie!
