So this is a recognised procedure?
Any problems with multi-coated lenses?

I have just acquired a Vivitar 70-210 series 1 zoom, which appears to have fungus on the inside of the very first element when viewed at certain angles. Otherwise it looks OK (see below)

If it works, this procedure sounds interesting, but I am a bit concerned about damaging the lens.

Any opinions?
